Question

Coulombs inverse square law states that force of attraction or repulsion between the
electric charges in a given medium is ... proportional to the product of strengths of two
charges and ... proportional to square of the distance between them​

Answer 1

Answer:

Directly, Inversely

Explanation:

According to Coulomb's Inverse Square Law,

$F = kQ_1Q_2/r^2$

Where $Q_1Q_2$ is the product of the strengths of the two charges and $r^2$ is the distance between the 2 charges squared.

So, Force is directly proportional to the product of the strengths of the two charges and inversely proportional to the square of the distance.
