Detailed explanation-1: -If the distance separating the objects is doubled, then what is the new force? Explanation: The electrostatic force is inversely related to the square of the separation distance. So if d is two times larger, then F is four times smaller-that is, one-fourth the original value.
Detailed explanation-2: -The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.
Detailed explanation-3: -So, when the distance between the two charges is halved, the force is increased four times.
Detailed explanation-4: -Hence, when the distance between the objects is reduced to half, the gravitational force increases four times.
Detailed explanation-5: -If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).
