Question

Charge q is 1 unit of distance away from the source charge S. Charge p is six times further away. The force exerted

between S and and q is __ the force exerted between S and p.
1/6
6 times
1/36
36 times

Answer 1

Fq = k q Q / R^2

Fp = k q Q / (6 R)^2

The force exerted between S and p is 1 / 36 of that between S and q

or the force between S and q is 36 times that between S and p.
