Question

The laws of forces that govern the force between two electric charges were discovered by :

• A. Faraday
• B. Ampere
• C. Ohm
• D. Coulumb

Answer 1

Answer: (D)

Coulumb

Coulomb stated that the force (F) of attraction or repulsion between two points charges $q_1$ and $q_2$ separated by a distance $r$ is proportional to the product of the magnitude of the two charges, and inversely proportional to the square of the distance of separation between them. i.e., $F\propto \frac{q_1{q}_2}{r^2}$
