Question

A current carrying closed loop in the form of an equilateral triangle pqr is placed in a uniform magnetic field in direction along pq. If the magnetic force on the arm qr is , then force on arm pr is

Answer 1

Answer:

____________________

Force along AB is zero as magnetic field is along AB.

The net force on a current carrying loop is always zero.

Fnet=F on AB+ F on BC + F on AC

0= 0+F+ (F on AC)

Hence , F on AC is -F
