Electrostatic force arises due to charge possessed by the electrons. It is calculated using Coulomb's law. Gravitational force arises due to mass possessed by the electrons. It is calculated using Newton's law of gravitation. To compare the two forces (or any two quantities), one way is to get their ratio.
Electrostatic force is
[Repulsion]
Gravitational force is
[Attraction]
Ratio of electric and gravitational force is
We conclude that:
(a) Electrostatic force is far more stronger than gravitational force.
(b) While studying interactions between light weight charged particles their gravitational interaction can be neglected.

(a) Is the induced charge appearing on the cavity wall distributed uniformly? What about the charge on the outer surface of the ball? Is that distributed uniformly?
(b) The point charge inside the cavity is moved away from the centre. Will the charge distribution on the outer surface of the ball change?
