Two positive ions, each carrying a charge q, are separated by a distance d. If F is the force of repulsion between the ions, the number of electrons missing from each ion will be (e being the charge of an electron)

4πε0 Fd2 e2 -
4πε0 Fe2 d2 -
4πε0 Fd2 e2 -
4πε0 Fd2 q2

Correct Option: C
Let n be the number of electrons missing.
| F = | . | |||
| 4πε0 | d2 |
⇒ q = √4πε0 d2 F = ne
| ∴ n = | | |
| e2 |
