A force is experienced by cathode rays when they pass through uniform electric field

A

In the direction of electric filed

B

In the direction opposite to that of electric field

C

Perpendicular to electric field

D

Zero ,because the cathode rays do not have the charge.

Text Solution

Verified by Experts

The correct Answer is:
B

While passing through the uniform electric field, cathod rays consisting of negatively charged particle ecperiences a force in the opposite direction to the electric field .
