In physics, there are four fundamental forces: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. However, the gravitational force is much weaker than the other three forces, so it is usually negligible in most situations.

Electric field and gravitational field are two different types of fields associated with electric charges and masses respectively. Electric fields are produced by electric charges and can be represented as vectors that have both magnitude and direction, pointing away from positive charges and toward negative charges. Gravitational fields are produced by masses and also can be represented as vectors pointing towards the source of the gravitational force.

Gravitational field and electric field are different phenomena and cannot be added directly to obtain a total field. The total field acting on a charged particle or a mass must be calculated by considering both electric and gravitational forces separately and then adding the forces vectorially.
