C) both energy and momentum changes
D) energy changes but momentum remains constant
Correct Answer: B
Solution :
Key Idea: Perpendicular magnetic force exerted due to magnetic field provides the required centripetal force to the particle for motion on circular path. When a particle with charge q enters a magnetic field B, the force acting on it, is \[F=qvB\]You need to login to perform this action.
