According to Coulomb's law, the electrical force between two charges is inversely proportional to the square of the distance between them. Thus, if the distance is halved (i.e., reduced to one-fourth), the force would be multiplied by [(1/2)^2] = 1/4. Therefore, if the distance between the two charges is halved, the electric force would be quadrupled (i.e., multiplied by 4). Hence, the correct answer is A.

When the Distance Between Two Charges Is Halved,the Electrical Force
