Answer 1

Answer:

thik hoo xd......

Anyway your answer ✔️

The magnetic force acts in such a way that the direction of the magnetic force and velocity are always perpendicular to each other. If force and velocity are perpendicular force and displacement are also perpendicular, thus W= FS cos q, if q = 90, work done will be zero.

Answer 2

Answer:

Now a force perpendicular to velocity can change the direction of velocity but can not change the magnitude of velocity. ... Since the force F due to the magnetic field is perpendicular to v the force will alter the path of the particle, but the work done by this force on the particle will be zero.
