Question
The attractive force between 2 charges is related to the distance between them as
✓

Answer

(b) $\frac{1}{r^2}$
Explanation: According to Coulomb's law the force between two charges is inversely proportional to the square of distance between the two charges. So $F \alpha \frac{1}{ r ^2}$.
