Assertion : The energy of a charged part...

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

A

If both assertion and reason are ture and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reson are false.

Text Solution

Verified by Experts

The correct Answer is:
D
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 `cos theta`] , so the energy of the charged particle does not change.
