Charge q is a unit of distance away from the source charge S. Charge p I'd two times further away. The force exerted between S and q is 4 times the force extended between S and q

The force exerted between s and q is four times that force between S and p

Explanation:

Given that ;

A source charge S

Is at a 1 unit distance from another charger q

The force between S and q is given by columbs law;

F=k*q*S/r^2

F= K*q*S/1

F= KqS ( this is the force between charges q and S)

Also charge between S and P at 2 units distance is

F=K*P*S/r^2

F= K*P*S/2^2

F=KpS/4

Hence 4F=KpS (This is the force between p and S)

It can be seen that 4F=4kqs=kpS

the answer to this is proletariats.
