The diagram below illustrates an arrangement of a cathode ray from an electron gun and a bar magnet placed perpendicularly to the direction of the ray. Will the ray bend downward or upward? Explain.

Explanation

The ray will bend upward. The direction of motion of the charge is due to the force acting on it which is mutually perpendicular to the direction of the magnetic field and the moving charge.
