MCQ
A negative charge is located in the uniform electric field between two plates $($not shown$).$
Where in the diagram will the electron have the greatest change in potential energy before hitting the one of the plates?
  • A
    $A$
  • ✓
    $B$
  • C
    $C$
  • D
    $D$
✓

Answer

Correct option: B.
$B$
A charged species tends to move from place of higher potential energy to that of lower potential energy.
The direction of electric field is from left to right. This means that there is a positively charged plate on the left side, closest to $A$ and farthest from $B.$
An electron being negatively charged plate always moves towards left here.
