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

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

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

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

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

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

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