Question

The work done by the magnetic force on a moving charged particle is:

पर्याय

• Equal to the kinetic energy of the particle

• Non-zero and positive

• Non-zero and negative

• Zero

Answer 1

Since the magnetic force is always perpendicular to the velocity of the particle, it has no component along the direction of motion. Therefore, no work is done by the magnetic force, and the kinetic energy of the particle remains constant.
