Question

In which of the following situations, the magnetic
field can accelerate a charge particle at rest?
1 When the magnetic field is uniform with respect
to time as well as position
II. When the magnetic field is time varying but
uniform w.r.t. position
Ill. When the magnetic field is time independent but
position dependent
(1) I, II & II
(2) III only
1 Il only
(4) None of these​

Answer 1

Answer:

1

Explanation:

it is because reason is at book

Answer 2

Answer:

4. None of these

Explanation:

A magnetic field exerts force only on moving charges F=BqVsinθ

hence a charge at rest will never experience a force in a magnetic field
