Q. A particle is moving in a uniform magnetic field, then
A) Its momentum changes but total energy remains the same
B) Both momentum and total energy remain the same
C) Both will change
D) Total energy changes but momentum remains the same
Explanation
(a) The charged particle moving in a magnetic field does not gain energy. However, the direction of its velocity changes continuously. Hence momentum changes
