What is electrostatic force ?

Why is electrostatic force conservative and central?

Two proton are kept at a separation of 40Å.F_(n) is the nuclear force and F_(e) is the electrostatic force between them . Then

Write any three characteristics of electrostatic force.

A test charge q_0 is placed at the centre of a spherical conductor of radius R. A charge Q is placed on the spherical conductor, What will be electrostatic force on the conductor due to q_0

Why is that gravitational force negligible compared to the electrostatic force between a proton and an electron? (Assume the distance between them as 1Å )

What is an electrostatic shielding? Mention its one application.

Compare electrostatic force with gravitational force and strong nuclear force.
