Question

doubt :?

Answer 1

when we slip from over a objet our body discharge charges right?

Answer 2

:? need a quick help plzzz

Answer 3

go on

Answer 4

first tell me the part i asid above is right or wrong? den i ll tellu my doubt

Answer 5

i am not a native speaker. will try to help

Answer 6

no it is not sure

Answer 7

Halliday Resnick Kreane volume 2
say it is not sure which body takes charges or which loose.

Answer 8

only if we are charged and object is conductor

Answer 9

but charge transferring takes place.

Answer 10

okay heena be a lil bit clearer. "when a body slips from our hands, it loses its charge" thats what you mean?

Answer 11

ok then tell me why we feel sensation of electric shock while opening door etc etc

Answer 12

and i am not realy dure what slip over exactly meens

Answer 13

slip means u r sitting on a couch suddenly u feel sm light y so?

Answer 14

here our body is having charge or its neutral?

Answer 15

because when you rub over any surface say on the carpet then there is the tranferring of charges take place either loosing or gaining of charges.
so when your boody lose or gain charge it implies your body might gain or lose electrons in simpler way*..

wo if you touch another object then it will cause sensation. because you were not neutral anymore.

Reference Halliday, Resnick and Krane Physics Volume 2

Answer 16

to feel that effect you mast be charged
there for for example you shoes are insulatos, yor clothes are from wool and synthetic material
friction during your mooving produses charges on you
due to isolatin shoes those charges stay on you
taching a condactor alows those charges to move (to you or from you) thas an ilectric current so feeling of shok.....

Answer 17

the question you asked heena it is related from law of conservation of charge.

Answer 18

@Shayaan_Mustafa tell me when we feel that charge our body is neutral or having charge

Answer 19

feel some light? you mean a slight electric shock?

okay that is because when you sit, due to friction and host of other factors, some charges transfer between you and the couch (remember the hair and comb experiment we did in junior classes? same mechanism). so the neutrality is disturbed. so now when you get up, and place your bare feet on the floor, the charges transfer back to the earth (which is like a huge charge sink, just like heat sink. any amount of charges can flow to it. Its like a huge potential sink) now as that charge flows through your body, you feel a slight shock like sensation. (and why we tremble is something that you bio student would be able to explain best :))

Answer 20

what u wanna say about polarisation @mos1635

Answer 21

charge. if it were neutral then it touching anyting will never create sensation madam.

Answer 22

it means when we touch a fur as i have a blanket og fur and some time not some times always i found light spark producing it wen i touch it??? it mean fur i already bearing a charge??

Answer 23

@apoorvk as u said abu the mechnism we did in juior clases that i did but never get y so i mean scale is neutral as well as paper bits are neutral still they attract how dey get polarised enough to attract each other??

Answer 24

yes. it is. therefore in dusty season the cloth we wear on our body stick to our body sometime. have you noticed this. shalwar qameez?

Answer 25

i dont wear that :P
anyways go on

Answer 26

and if u are taking season point here then i ll say i saw that sparks everytime when ever i touch it or play with dat sparks :P

Answer 27

ok now i think i get the question:
friction causes charges to moove from body to cloth
total charge should be =0 there for neutral body
is that your point?

Answer 28

loll... i play with that in my childhood. but girls remain childish in their adultry too. hehehehe...

Answer 29

no moss i m asking dat when we touch a fur blanket we fell some shck or say say some sparks too it means that our body is behaving as a source for blanket to produce that sparks??

Answer 30

Stuff is neutral under normal circumstances but we may acquire charge.

substances have "tendencies". Suppose a substance is like a bit of electro-positive in nature. it will want to be positively charged. similarly for an electronegative thing.

Now when you are sitting with the fur around your skin, the two substances have different tendencies. As they come in contact, rub against each other, some loose electrons flow from one body to another (which to which I don't know, but yes there is net flow).

so now ofcourse both substances charged. Now when you are done lazing around, and get up from your bed, as your bare feet touch the ground, all the charge that your body had accumulated flows from your body through your feet to the ground. why? because the earth is like a massive body having a huge potential (remember what happens in earthing)

Answer 31

mos1635 is right if he is trying to say body must be neutral.

Answer 32

An now why the sparks appear....

Answer 33

arrey yar shayaan i just notice dat ok i was just doing an experiment u can say observation abu dat so its necessary for me to play wid it :P

Answer 34

ok one more as general not from any books i m aksing that we feel sometimes current shck by touching any object i mean we dont knw which object as when we tch wood steel we feel smtimes any reason?

Answer 35

to understand this method you must suppose either body is positively charge or negatively.

Answer 36

wood?? a complete insulator.. O_O

Answer 37

i knw dats y i mention wood as i also studied wood is complete inuslator in most of the books but i still feel smtimes current u can say by touching it suddenly .. O.o

Answer 38

now now...


now when you are on your bed, with the fur around you and the charge has already flown. so . so what? there is kind off potential difference between the two surfaces due to different charges present.
now when the two surfaces are brought closer.. (i will give you an anomalous example, just like you bring magnets close to each other). after a certain point the potential strength gets so high that there is an "electrical breakdown" that means at that point the charges literally flow through the air into the other body to achieve neutrality!!!!! basically at that point the air becomes a conductor!!!(you ll read more in the capacitors section). and when that charge flows through the air, it causes all sorts of energy releases, leading to sparks and that 'crackling' sound.

Answer 39

air becomes conductorr.... haaw.w... O_O

Answer 40

i am toring my electronics degree... :(

Answer 41

hmm... i think i m gettin thnQ guys :)

Answer 42

yes sir. at that moment the charges are literally flowing through "air". Okay it is not a conductor (according to definition of conductivity) but it is actually conducting at that point!

Answer 43

ok dear if you say then may be it is right.. what can i say more..

Answer 44

:s

Answer 45

@shayaan what are you studying btw? and please enlighten me if i am wrong 'cause am definitely not perfect, I promise ;)

Answer 46

i am doing electronics engineering dost.

Answer 47

read my profile.. :D

Answer 48

ohkay.. so heena mudde ki baat. kuch samajh mein aaya>

Answer 49

ha :)

Answer 50

good.:)

Answer 51

hehehe... not only me. everyone knows this. right apoorvk. :D lol

Answer 52

nah apoorv is new here he dunno abu my phyc :P but soone he gonna know me :P

Answer 53

Everyone knows what?

Answer 54

heena. you are right. apoorvk proved you right. lol.

Answer 55

hehe soon u ll get to knw dat apoorv ok nw lemme do my wrok but be around ok

Answer 56

What do I need to knwo about your physics? C'mon please don't post questions if you know them already, and are just curious if others know it as well. It takes a whole lot of patience to type all that (which I rarely have)!! -\(o.O)/-

Answer 57

ok until i do calculus frnds. good luck and thx for everyone who contributed here.

Answer 58

hey angular position in YDSE means angular fringe width right??

Answer 59

@Shayaan_Mustafa @apoorvk ???

Answer 60

young double slit experiment they said abu angular position what dey mean by it :?

Answer 61

as i see the solution and found thay use symbol theta which we use for angular fringe width :?

Answer 62

bola tha na yahi p rhna bhag gye aplog ab milo mje btati hu dono ko !!!!!!!!!!!!!

Answer 63

Arey ye line last waali toh main abhi padha. Udi baaba, mujhe bahut dar lag raha hai. Koi Bachao!!! :P
