Question

In Coulomb's Law, why the Force(F) is inversely proportional to r², why not is inversely proportional to r?

Answer 1

The magnitude of the electric force between q 1 q_1 q1q, start subscript, 1, end subscript and q 2 q_2 q2q, start subscript, 2, end subscript is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them. This equation is known as Coulomb's Law.
