Question

The work done by a magnetic field, on a moving
charge is
(a) zero because F➝ acts parallel to v➝
(b) positive because F➝ acts perpendicular to v➝
(c) zero because F ➝ acts perpendicular to v➝
(d) negative because F ➝ acts parallel to v ➝

Answer 1

Answer:

option (c)

Explanation:

since Force on a moving charge due to magnetic field is perpendicular to the motion, the work done is zero.

F = q v×B

hence option (c)
