Represent the force between the two point charges in terms of position vectro graphically.

The electrostatic force between two point charges is directly proportional to the

Coulombian force between two charges ………….

Which of the following graphs represents the relationship between the force F between two point charges and the distance r between them :

Correct the following statement. The Couolmb force between two point charges is a short range force.

Write general expression for force between two point charges.

Electrostatic forces between two point charges is called central force. Why?

Coulomb’s law for electrostatic force between two point charges and Newton’s Jaw of gravitational force between dependence on the distance between the charges/ masses. Compare the strength of these forces by determining the ratio of their magnitudes : for two protons.
