Assertion: When a magnetic dipole is placed in a non uniform magnetic field, only a torque acts on the dipole.
Reason: Force would also acts on dipole if magnetic field were uniform.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

D

Explanation

In a non-uniform magnetic field, both torque and net force acts on the dipole. If magnetic field were uniform, net force on dipole would be zero
