Compare the electrostatic force acting between two charged particles and the gravitational force acting between them.

The electrostatic force between two charges is a 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.

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 an electron and a proton and

Coulomb's law for electrostatic force between two point charges and Newton's law for gravitational force between two stationary point masses, both have inverse-square dependence on the distance between the charges/masses. Compare the strength of these forces by determining the ratio of their magnitudes (i) for an electron and a proton and (ii) for two protons

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

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

Mention one similarity between Coulomb force and gravitational force acting between two stationary charges.
