Question -

An electron enters with its velocity in the direction of the uniform electric lines of force. Consider lines of force to be straight. Then

Options:

A . The path of the electron will be a circle

B . The path of the electron will be a parabola

C . The magnitude of velocity of the electron will first decrease and then increase

D . The magnitude of velocity of the electron will first increase and then decrease

Answer: Option C
:
C

As electric field applies the force on electron in the direction opposite to it’s motion, the velocity of the electron will decrease.
