Q. When a charged particle moves perpendicular to a uniform magnetic field, then
COMEDK
COMEDK 2009
Moving Charges and Magnetism
A
its momentum changes, total energy is same
44%
B
both momentum and total energy remain the same
28%
C
both momentum and its total energy will change
17%
D
total energy changes, momentum remains same
11%
Solution:
As magnetic force acting on a charged particle moving in a uniform magnetic field does no work, so its energy will be same. But velocity of the particle changes continuously so its momentum changes
