GENERAL KNOWLEDGE

Detailed explanation-1: -Unlike the other two fields, which can involve both attraction and repulsion, gravity only acts by attraction.

Detailed explanation-2: -Another major difference between the two forces is that gravitational force can only be attractive, whereas electrostatic could be attractive or repulsive, depending on the sign of charges; unlike charges attract and like charges repel.

Detailed explanation-3: -The gravitational force is always attractive in nature. A body that has mass always attracts another body having mass and the force between them is given by Newton’s law of gravitation. If there were repulsive gravitational forces, it would imply that the body has negative mass which is not possible.

Detailed explanation-4: -Electromagnetic force is a special force that affects everything in the universe because it has an infinite-range attractive, like gravity; it is also a repulsive force which acts between charged particles.
