Magnetic field

A

can increase the speed of charged particle

B

can accelerate a charged particle

C

both a and b are correct

D

both a and b are incorrect

Text Solution

Verified by Experts

The correct Answer is:
b
Magnetic field can accelerate a charged particle by changing the direction of its velocity but it cannot change the speed of charged particle as magnetic force always acts perpendicular to the velocity of charged particle.
