If the distance between two electric charges is halved, then the value of electric force between them will become

If the distance between two electric charges is halved, the value of the electric force between them will become quadruple (option C). This outcome is based on the principle that the electric force between two charges depends on the distance separating them. When the distance between the charges is reduced by half, the electric force does not merely double; instead, it increases by a factor of four. This is because the relationship between the distance and the force is such that reducing the distance by a certain factor results in the force increasing by the square of that factor. Therefore, when the distance is halved, the force becomes four times stronger, illustrating how sensitive the electric force is to changes in distance.
