Question

what is electrostatic force

Answer 1

Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing. The Greek word for amber, ήλεκτρον, or electron, was the source of the word 'electricity'.

Answer 2

The attractive or repulsive interaction between any two charged objects is an electric force. Like any force, its effect upon objects is described by Newton's laws of motion.
