Answer to Question #160131 in Field Theory for wilder

Question

Explain in what ways the Coulomb force between two charged particles is (i) different (ii) similar, to the gravitational force between two masses.

Answer 1

Similarities

Coulomb force and gravitational force both are indirectly proportion to distance between objects.

They both act between two bodies without any means of contact.

Difference

Gravitational force are only attractive while electric field can be attractive and repulsive. Electric field is much stronger than gravitational field.
