A current carrying wire PQ is placed near an another long current carrying wire RS . If free to moves , wire will be have

Options

A. rotational motion only
B. translational motion only
C. rotational as well as translational motion
D. neither rotatioanl nor translational motion.

Answer

C

Explanation

Since the magnetic field, due to current through wire CD at various locations on wire AB is not uniform, therefore, the wire AB, carrying current `I_(1)` is subjected to variable magnetic field due to which, neither the forece nor the torque on the wire AB will be zero. As a result of which the wire AB will have both translational and rotational motions.
