Force f acts between two charges, q1 and q2, separated by a distance d. if q1 is increased to twice its original value and the distance between the charges is also doubled, what is the new force acting between the charges in terms of f? f f f 2f

Okay, haven't done physics in years, let's see if I remember this.

So Coulomb's Law states that  so if we double the charge on  and double the distance to  we plug these into the equation to find



So we see the new force is exactly 1/2 of the old force so your answer should be  if I can remember my physics correctly.
