help please!
the force between two long parallel conductors is 15 kg/metre. the conductor spacing is 10 cm. If one conductor carries twice the current of the other, calculate the current in each conductor.

help me analyze please.

lilMissMindset: Don't ask the same question in multiple groups. "mathematics" is the wrong one anyways. -> http://openstudy.com/code-of-conduct

shubhamsrg · Answer

if you can tell, what is the expression of force per unit length between 2 infinite parallel current carrying wires ?

anonymous · Answer

@MuH4hA  sorry. im going to erase my other questions on other groups.

anonymous · Answer

Okay :)

(although - you _should_ ask physics-question in physics... but i am no mod, so idk - guess it's ok ;) )

anonymous · Answer

@shubhamsrg  the expression of force per unit length b/w two conductors: 
(F2/L)=(u0*i1*i2)/2pi*d

shubhamsrg · Answer

@stgreen i knew that buddy and i wanted @lilMissMindset to ans my query, ofcorse//

anonymous · Answer

i see

anonymous · Answer

yea, saw it now. 
(F2/L)=(u0*i1*i2)/2pi*d

shubhamsrg · Answer

so where are you stuck..just plug in values given..cant be that difficult

anonymous · Answer

what value should i put in 2pi*D?

anonymous · Answer

is D the distance?

shubhamsrg · Answer

D is distance between the wires (in meters)

anonymous · Answer

how about permeability? what is its unit?

anonymous · Answer

oops sorry µ0 = 4π×10−7 ≈ 1.2566370614…×10−6 H·m−1 or N·A−2

anonymous · Answer

its henry per metre

anonymous · Answer

or newton per ampere?

shubhamsrg · Answer

dont worry about unit of Uo ,, just plug in everything in meters and kgs and you should get an ans in ampere..

shubhamsrg · Answer

all conventional units..

anonymous · Answer

aw, sorry, im being stupid. im having trouble with the unit. :(

anonymous · Answer

no no you u0 is in newton per ampere square..while the force you have is in Kg..convert your force in newtons first

shubhamsrg · Answer

i see..yes ,you have to convert that..

use mg = F for that conversion..

anonymous · Answer

aww. thank you so much! at last, i get this problem. :)

anonymous · Answer

@MuH4hA i got an answer in the mathematics group.

anonymous · Answer

MATHS section got a number of engineers too lady :P

anonymous · Answer

yea, that is why i put my questions in multiple groups, hoping for answers. not knowing, it is wrong according to codes of conduct. im one guilty student.

anonymous · Answer

uh-oh come on...its not such a CRIME lol

anonymous · Answer

right. lol

anonymous · Answer

thanks again. ;)
