Detailed explanation-1: -In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

Detailed explanation-2: -Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases. And by whatever factor the distance is changed, the electric field strength will change inversely by the square of that factor.

Detailed explanation-3: -The strength of an electric force depends on the size, or magnitude, of the charges and the distance between them.

Detailed explanation-4: -The magnitude of the electrostatic force F between two point charges q1 and q2 is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. Like charges repel each other, and opposite charges mutually attract.

Detailed explanation-5: -Answer and Explanation: In the given statement (c) is true, Electric forces cause the objects to repel or attract each other.
