Question

According to Coulomb's law, how does distance affect electric force?A.The electric force is the same no matter how far apart the objects are.B.Objects must be in contact with one another for the electric force to have an effect.C.Only sometimes can the electric force act without objects touching.D.Electric force can act at a distance but is stronger when objects are closer.

Answer 1

According to Coulomb's law,

`Force\text{ }\propto(1)/((distance)^2)`

Thus, electric force can act at a distance but is stronger when objects are closer.

Hence, option D is correct.
