Gravity is strictly an attractive force.
differentiate attractive force from repulsive pulse
Electric force is the attractive or repulsive force between two charged particles. The potential difference between two points can be measured with a Voltmeter.
Both have the concept of variation of force inversely with the square of the distance. But in case of coulomb we have electric charges and in case of newton's gravitation law we have masses. Coulomb's force can be either attractive and repulsive where as Newton's is only attractive
Electrostatic forces
The gravitational force is only attractive. Electric and magnetic forces can be both attractive and repulsive.
All mass has the same sign, while electric charge can be either positive or negative.
Gravity is strictly an attractive force.
In the same direction, attractive not repulsive, and many tens of orders of magnitude smaller.
Electric force is the attractive or repulsive force between two charged particles. The potential difference between two points can be measured with a Voltmeter.
differentiate attractive force from repulsive pulse
Gravitational force exists between masses. Gravitational force is only of attractive. No repulsive gravitational force has been found so far. But in electrostatics and magnetism, the force between electric charges and magnetic poles respectively are of both repulsive and attractive. Nuclear force between the nucleons within the nucleus of the atom is also attractive in nature.

Electrostatic forces
An electric current is the result of a voltage. Considering the individual charged particles (often these are electrons), they must be subjected to electric forces - for typically an attractive force to one side, and a repulsive force to the other.
