MCQ
Two charges are placed at certain distance apart. A metallic sheet is placed between them. What will happen to the force between the charges?
  • A
    Increases
  • ✓
    Decreases
  • C
    Remains the same
  • D
    May increase or decrease depending upon the shape of the metallic sheet
✓

Answer

Correct option: B.
Decreases

Force will decreases because when medium is inserted between then it will reduces the forces by its permitivity. the force becomes
$\text{Fe}_\text{m}=\frac{\text{Fe}}{\in_\text{r}}$
