COMEDK
COMEDK 2015
Moving Charges and Magnetism
A
only the electric field
55%
B
only the magnetic field
15%
C
both the fields
26%
D
none of the fields.
4%
Solution:
Magnetic force does no work on the charged particle. Hence, gain in kinetic energy of a charged particle in a cyclotron depends only on electric field.
