Difference between Coulombic and gravitational forces

[MarianKh]

Could some one help me understand the difference and the similarties between Coulombic fundamental force and Gravitational fundamental force?

Coloumb is used to find forces between the electric charges, while Gravitational force is used to find the force of a falling object.

but what are the similarties?
thank you so much

but what are the similarties?

Write down the equations for both, then we can look at them and discuss them.
