How would you change the distance between two charged particles to increase the electric force between them by a factor of 16?
A. Reduce the distance by a factor of 4.
B. Increase the distance by a factor of 16.
C. Increase the distance by a factor of 4.
D. Reduce the distance by a factor of 16.

Respuesta :

A. Electric 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.

Answer:

A. Reduce the distance by a factor of 4.
