Question

The force of interaction (attraction or repulsion) between two stationary point charges in vacuum is _____

• A. directly proportional to the product of the charges
• B. inversely proportional to the product of the charges
• C. directly proportional to only the lower of the charges
• D. inversely proportional to only the lower of the charges

Answer 1

The correct option is A directly proportional to the product of the charges

Electrostatic force=$F=\frac{q_1{q}_2}{4\pi {ϵ}_o{r}^2}$

Hence, force of interaction is directly proportional to the product of charges.

Answer-(A)
