Question

Similarities between gravitational force and electrotatic force

Answer 1

Both gravitational force and electrostatic force attract news that both approach

Answer 2

Three similarities between electrostatic and gravitational forces are :  Both of them are inverse square forces, i.e. they fall of as 1/r^2 where r is the distance between the two particles. Both of them are central forces, i.e. angular momentum conservation occurs. The forces are conservative.
