What is the force exerted by a charged body on another charged body called?

This question was previously asked in
RRB Group D 2018 Question Paper (11-Oct-2018) (Shift 3)
The correct answer is

Electrostatic force

The force that one charged body exerts on another simply because both of them carry electric charge is called the electrostatic force or Coulomb force, given by F = kq₁q₂/r²; it is attractive between unlike charges and repulsive between like charges.

Gravitational force acts between masses, centripetal force is the net inward force needed for circular motion and frictional force opposes relative sliding between surfaces, so none of them is caused by the charges on the bodies themselves.

Hence, Electrostatic force.
