Question

Two like charges are placed a certain distance apart in air. If a brass plate is introduced between them, the force between the two charges will

• A. increase
• B. decrease
• C. remain the same
• D. become zero

Answer 1

The correct option is C remain the same

They are like charges so they will repel each other.

If a metal plate is in between them, then its electrons will get pushed away if the two charges are negative and pulled if positive.

In both the cases, the brass plate's electrons undergo forces in opposite directions. Hence they will cancel each other and nothing will happen to the electrons.

An unaffected plate when placed between two charges doesn't affect the force between the two charges.
