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.
