## Homework Equations

V=KQ

_{1}/r

## The Attempt at a Solution

I used the above formula to...

(9.0 x 10

^{9})(4.0 x 10

^{-6})/1 = 36000V

(9.0 x 10

^{9})(1.0 x 10

^{-6})/0.5 = 18000V

Now the answer is 54000V and I'm just wondering if that's the answer because you take 36000J + 18000V = 54000V?
