Q. A.charged particle moves along a circle under the action
of magnetic aed electric fields, then this region of space
may have

A

E=0, B=0

B

C

D

Solution:

A charged particle moves in a straight line under the action of
an electric field whereas it moves in a circular path under the
action of a magnetic field. Thus, for the particle moving in a
circular path, E = 0,
