(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two test charges are brought separately into the vicinity of charge +Q. First the test charge +q is brought to a point A, a distance r from +Q. Next, +q is removed and a test charge +3q is broguht to a point B, a distance 2r from +Q. Compared with the electric potential of +Q at point A, that of +Q at B is how much that of A. The choices are tiwce that of A, 1.5 times, the same as A, half of A, or 3/4 that of A

2. Relevant equations

I was using the equation kq/r for electric potential and plugging in numbers but I'm unsure what to else to do.

3. The attempt at a solution
