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 q is _____ the force exerted between S and p.

Answer 1

Use Coulomb's law:

F=Q1*Q2/(4πr²ε₀)

Where
Q1, Q2 are magnitudes of point charges
r=distance between Q1 and Q2
ε₀ = 8.854*10^-12

So we conclude that the forces between point charges are directly proportional to the product of the charges, and inversely proportional to the square of the distance between them.

For example, two charges P1 & P2 placed at 1 cm apart will experience 4 times the force if they had been placed 2 cm apart, assuming there are no other charges in the vicinity.
