If two charged bodies attract each other with a force of 1 newton, with what force will they attract each other if the distance between them is reduced to one-half of its original size? (The “newton,” abbreviated by the letter N, is the unit of force in the metric system. This is like the “pound” in the system that you are used to. Contrary to the way that most people use it, the kilogram is not a unit of force but a unit of mass.)

2. Relevant equations

F = k Qq/d2

k = 9 x 10^9

3. The attempt at a solution

I sketched out my picture then a subsequent sketch with my distance cut in half:

(+)---->1N 1N<----(-)

(+)--> <--(-)

I don't know how I am supposed to figure this new force without knowing the Q values or distance! I am only guessing that since the objects are twice as close, this causes the force to double. But honestly, I don't know how to back this up numerically without additional information! Someone please tutor me to understand these concepts better.
