An electron entres a magnetic field whose direction is perpendicualr to the velocity of the electron. Then

A

The speed of the electron will increase

B

The speed of the electron will decrease

C

The speed of the electron will remain the same.

D

The velocity fo the electron will remain the same.

Text Solution

Verified by Experts

The correct Answer is:
C
Force acts perpendicular to the velocity in a magnetic field, so speed of electron will remain the same.
