comparison of electrostatic and gravitational force between earth and moon??

Answer 1

While the electric force is in general a much, much stronger force than gravity, electrical forces are not always attractive (e.g. plus and minus charges attract, while two positive or two negative charges will repel each other). So, while all matter is made of atoms with positively and negatively charged parts (protons and electrons respectively), the vast majority of atoms have an equal amount of positive and negative charge on them, so have no net charge, and thus don't really exert any electric force.

On the contrary, as far as we know, gravity is always attractive. There is no known way of making two masses repel each other via gravity. So though gravity is weaker in its own right, gravity tends to add up, while electrical forces tend to balance each other out.

This is true between the Earth and Moon. There basically is no electric force between the Earth and Moon (or if there is, it's so small that it's not important). But there is a significant gravitational force between the Earth and Moon, which results in the Moon going around the Earth.

Answer 2

Gravitational >>> Electrostatic.

Answer 3

They are not same.
