Question

A positively charged particle is released from rest in a region of uniform electric field. The particle will move:

• A. with constant speed
• B. with constant velocity
• C. with constant acceleration
• D. with variable acceleration

Answer 1

The correct option is C with constant acceleration

$F=qE$

$a=\frac{F}{m}=\frac{qE}{m}$

If $E$ is uniform then $a$ is constant.
