A conductor PQRSTU, each side of length L, bent as shown in the figure, carries a current i and is placed in a uniform magnetic induction B directed parallel to the positive Y-axis. The force experience by the wire and its direction are

Text Solution
Verified by ExpertsThe correct answer is:
C
As PQ and UT are parallel to Q, therefore 
The current in TS and RQ are in mutually opposite direction. Hence, 
Therefore the force will act only on the segment SR whose value is Bil and it’s direction is +z.
