An electron enters in an electric field with its velocity in the direction of the electric lines of force. Then

A

The path of the electron will be a circle

B

The path of the electron will be a parabola

C

The path of the electron will decrease

D

The velocity of the electron will increase

Answer

Correct option is.   C The path of the electron will decrease

the velocity of the electron will decrease just after entry

When an electron enters an electric field with its velocity in the direction of the electric lines of field, then the velocity of the electron will decrease just after entry due to the lines of force of the electric field.
