Assertion (A):?Work done by magnetic force on a charged particle moving in uniform magnetic field is zero.
Reason (R):?Path of a charged particle in uniform magnetic field, projected in the direction of field, will be a straight line.
Dear student,
A charge directed in same direction of magnetic field passes undeflected,
Reason is also true but it is not correct explanation of assertion.

The force on a charged particle moving in a uniform magnetic field always acts in the direction perpendicular to the direction of motion of the charge, that's why work done is zero.
Assertion is true.A charge directed in same direction of magnetic field passes undeflected,
Reason is also true but it is not correct explanation of assertion.
