Best ResponseYou've already chosen the best response.0I believe.. regardless of what the current direction or for that matter the magnitude in the middle wire is, the answer should be zero! . But not in the options!

Best ResponseYou've already chosen the best response.0I think the problem is wrong, it should be calculate the force on the conductor C

Best ResponseYou've already chosen the best response.0Please check this one http://faculty.kfupm.edu.sa/phys/kuhaili/PHYS102Exams_T111/Chapter29.pdf question number 23.. even that is wrong ?.. cause regardless of what direction or magnitude current is.. net force has to be zero!

Best ResponseYou've already chosen the best response.1no, if current in wire 2 is in the opposite direction to current in wire 1. the net force on 3 would be zero.

Best ResponseYou've already chosen the best response.1But you also need a certain magnitude to make it zero.

Best ResponseYou've already chosen the best response.0No the question is, what is the net force on WIRE 2, the middle wire.. As long as the current in side 2 wires are same and in same direction, the force on wire 2 will always be zero!

Best ResponseYou've already chosen the best response.1\[\frac{\mu L I_2}{2\pi \cdot \frac12 } = \frac{\mu L I_1}{2\pi \cdot 1} \implies I_2 = \frac{I_1}{2}\]

Best ResponseYou've already chosen the best response.0oh yea.. in the question 23 its the WIRE 3.. correct.. there also i read as wire 2.. I am sorry!!.. you are right .. !!
