State and explain Coulomb,s law in electrostatics.

Explanation

Statement:The electrostatic (or electric)Force between two point charges in directly proportional to the product of the magnitude of the two charges and inversely proportional to the square of the distance between them.
Explanation :Let `q_(1),q_(2)` be the two point charges separted by a distance r in vaccum ,then magnitude of electrostatic force (F) between the charges is
`F=k(|q_(1)q_(2)|)/(r^(2))` ,where `k=(1)/(4piepsi_(0))` is a constant .
