A positively charge particle moving along `x`-axis with a certain velocity enters a uniform electric field directed along positively y-axis. Its

A

Vertical velocity changes but horizontal velocity remains constant

B

Horizontal velocity changes but vertical velocity remains constant

C

Both vertical and horizontal velocities change

D

Neither vertical nor horizontal velocity changes

Text Solution

Verified by Experts

The correct Answer is:
A
Since `a_y = (qE)/m`
`a_x =0`
`v_x` = constant.
