Select the correct statement:

Options

A. The speed of a charged particle may increase in a non-uniform magnetic field.
B. The speed of a charged particle may increase in a uniform magnetic field.
C. A charged particle can be accelerated by a magnetic field.
D. A charged particle cannot be accelerated by a magnetic field.

Answer

c

Explanation

Magnetic force acts perpendicular to velocity and hence it can only produce normal acceleration, which changes the direction of motion. Due to no tangential acceleration, the speed of the particle cannot change. Hence, option (c) is correct
