MCQ

In the following figure two parallel metallic plates are maintained at different potential. If an electron is released midway between the plates, it will move

A
Right ward at constant speed
B
Left ward at constant speed
C
Accelerated right ward
✓
Accelerated left ward

✓

Answer

Correct option: D.

Accelerated left ward

d
(d) Electric field is directed right ward (higher potential of $-200\, V $ to lower potential of $-400\, V$). When electron left free in an electric it accelerates opposite to the electric field. Hence in the given case electron accelerates left ward.
