9. What happens to the electric force between two point charges if the magnitude of both charges is doubled, and the distance between them is halved?

  • A. The force is halved.
  • B. The force remains the same.
  • C. The force is quadrupled.
  • D. The force increases by a factor of 16.

Correct Answer: D

Explanation:

D

Coulomb's Law is given by

Doubling each charge, and halving the distance between them yields
