How would you change the distance between two charged particles to increase the electric force between them by a factor of 16?

AReduce the distance by a factor of 4.
BIncrease the distance by a factor of 16.
CIncrease the distance by a factor of 4.
DReduce the distance by a factor of 16.

AElectric force follows an inverse square law, meaning electric force is inversely proportional to the square of distance between them. F = k/r^2. For F to be multiplied by 16, r^2, the denominator, should be multiplied by 1/16, and hence, r should be multiplied by 1/4.
