Question

The force of interaction (attraction or repulsion) between two stationary point charges in vacuum is directly proportional to the product of the charges and inversely proportional to the square of distance between them. This is called_______

• A. Curie's Law
• B. Coulomb's law
• C. Faraday's Law
• D. Ampere's Law

Answer 1

The correct option is B Coulomb's law

The given statement is of Coulomb;s law which states that force between two stationary point charges is $F=\frac{1}{4\pi {\epsilon }_0}\frac{q_1{q}_2}{r^2}$

where $q_1$ and $q_2$ are two stationary point charges and $r$ is the distance between them.

$\frac{1}{4\pi {\epsilon }_0}=$ constant of prportionality.
