Question 1

Two identical point charges are separated by a distance r in vacuum. If the distance becomes 2r, the electrostatic force becomes:

F=kq2r2F = \frac{kq^2}{r^2}
  1. A

    Four times the original force

  2. B

    Twice the original force

  3. C

    Half the original force

  4. D

    One-fourth of the original force
