Step-by-step explanation:
Electric force or electrostatic force is the force between two or more charged particles.It can be attractive or repulsive because two similar charges repel each other and opposite charges attract each other.For instance a positive and a positive charge will repel each and a positive and a negative charge will attract each other.
Meanwhile gravitational force is attraction between two bodies(two masses) due to gravity.They always attract each other.The force of attraction by gravity us dependent on sqaure of distance between the two bodies and the product of their masses.
