(b) along a parabolic path
(c) along a straight line
(d) in an elliptical orbit.
Correct Answer:
in a circular orbit
Explanation:
If the electric field switched off, and the same magnetic field is maintained, the electrons move in a ciruclar orbit and electron will travel a magnetic field to its velocity.
