A beam of electron passes undeflected through mutually perpendicular

A beam of electron passes undeflected through mutually perpendicular electric and magnetic fields. If the electric field is switched off, and the same magnetic field is maintained, the electrons move

Options

(a) in a circular orbit
(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.
