Answer #1

a)We know that coulomb's law

If we tripling one of the charges then the force between two charged objects is tripled

b)

Gravitational force originates from the mass of the body and electrostatic force originates from the charge of the body.

Electrostatic force is attractive and repulsive but gravitational force is attractive only

Both follow inverse square law with respect to distance, but gravitational force is very weak as compared to electrostatic force between two bodies.

the neutrons exert only gravitational force on each other because they don't have charge. the electrons and protons have both charge and mass, so they exert both electrostatic and gravitational force, but the strength of electrostatic force is very large than gravitational force.
