Question

Please help :)

Answer 1

@Callisto @Ishaan94 @ParthKohli

Answer 2

How do we find this out?....any graphical method?

Answer 3

what is your qustion ?

Answer 4

its there written in the top?

Answer 5

what can i helpe you

Answer 6

i need to know how to find the centre of mass? and i need to know the explanation

Answer 7

@apoorvk

Answer 8

can you find AC using Pythagorean theorem?

Answer 9

huh....its the centre of mass they are asking for?

Answer 10

an electric current is formed when a conducive pass is created to allow free electrons to continuously moved

Answer 11

your image link opened up a different image earlier - some bug may be. okay now..

Answer 12

Okay what do you think is the possible answer?

Answer 13

is that for me? boss

Answer 14

@apoorvk i think its B, but i donno, if a familliar question like this comes, i m not able to assure my answer

Answer 15

Okay, A is simply not possible right? Do you agree?

Answer 16

The answer is assured here. Just follow me.

Answer 17

sure..

Answer 18

Do you see that that B is almost at the middle of the body, but the mass is concentrated more towards the lower portion?

Answer 19

or rather B can even be considered lying in the upper half of the body, right?

Answer 20

but how do we know that..

Answer 21

by visual instinct what else? by looking.. do you agree that the mass of the lower half is more than the upper half?

Answer 22

yes then?

Answer 23

Answer is "A".The center of gravity of an object is the balance point around which there are equal moment arms of length times weight. The object can act as if all its weight was concentrated at the centre of gravity. Just spin the card,holding the pin,the card rotates at point A which is the centre of gravity.

Answer 24

thats not the answer bro..

Answer 25

the answer is B. in this case just by careful analyzing we can say that.

Answer 26

hm okay...thnks

Answer 27

but the answer is C...i checked the marking scheme...@apoorvk @ramkrishna

Answer 28

if you want to find it out with some experiment then take two points E and F (shown in attached figure) and hand it out at these points and then draw the vertical lines.

center of mass is that point where all the three lines intersect .

Answer 29

i know it's C. because the CoM will be shifted towards the place where the mass is more concentrated. - i asked you to follow me man -_-

Answer 30

ofcourse can't be at the bottom most point, i.e. 'D'

Answer 31

sorry. answer is C by mistake i wrote B.

Answer 32

i dint get u @apoorvk, whats CoM?

Answer 33

@zaphod did you understand the experimental method of finding the center of mass (COM)

Answer 34

@ramkrishna CAN U SHOW ME IT IN A DIAGRAM

Answer 35

i have two system of particles - edit my diagram and show me what the approximate location of CoM would be acc. to you?
