Q1

Assertion (A) : The deflecting torque acting on a current carrying loop is zero when its plane is perpendicular to the direction of magnetic field.

Reason (R) : The deflecting torque acting on a loop of magnetic moment \(\vec{m}\) in a magnetic field \(\vec{B}\) is given by the dot product of \(\vec{m}\) and \(\vec{B}\).

a

Both Assertion (A) and Reason (R) are true and (R) is the correct explanation of (A).

b

Both Assertion (A) and Reason (R) are true and (R) is NOT the correct explanation of (A).
