resemblance of coulomb's law and gravitational law

Coulomb's law tells about the electrosatic force between two charges, on other hand gravitational law tells about the gravitational force between any two masses.
The electrosatic force is either attractive or repulsive depending on the charges(positive, negative)

From above, the value of K is more and more than the value of G.
From this, we can conclude that the value of electrostatic force is greater than gravitational force. Due to this reason, in nature, even every substance is made up of atoms contains electrons, protons(which causes electricity), electrostatic force does not occur because they uncharged, so that we can gravitational force occurs between them. So, they are fix up to the earth.
