Gravitational as well as electrostatic force always act along the line joining the two objects.

Vedclass · Answer

(C) $1$. Gravitational force is much weaker than electrostatic force. Thus,option $A$ is incorrect.$2$. Gravitational force is always attractive,but electrostatic force can be attractive or repulsive depending on the charges. Thus,option $B$ is incorrect.$3$. Both gravitational force (Newton's Law of Gravitation) and electrostatic force (Coulomb's Law) are central forces,meaning they act along the line joining the centers of the two objects. Thus,option $C$ is correct.$4$. Both gravitational force and electrostatic force follow the inverse square law $(F \propto \frac{1}{r^2})$. Thus,option $D$ is incorrect.
