Assertion: The energy of charged particle moving in uniform magnetic field does not change.
Reason: Work done by magnetic field on the charge is zero.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
The force on a charged particle moving in a uniform magnetic field always acts in direction perpendicular to the direction of motion of the charge. As work done by magnetic field on the charge is zero, `[W = FS costheta]`, so the energy of the charged particle does not change.
