A charge of 0.611 nC is placed at the origin. Another charge of 0.383 nC is placed at x1 = 8.1 cm on the x-axis.

At which point on the x-axis does this potential have a minimum?

2. Relevant equations

U=(kq1q2)/r

3. The attempt at a solution

I really have no idea how to even start this problem. I've been thinking about it for a couple hours now. Any help would be appreciated.
