## Homework Statement

What is the electric potential at the point indicated with the dot in the figure?

The dot is in the center of an equilateral triangle with sides of 3 cm. The top point is a +2 uC charge and the bottom points are both -1 uC charges.

## Homework Equations

V= kq/r

## The Attempt at a Solution

I used 1.299 cm the distance from the center point to the charges. I then plugged in the values for each point and added them up. I DID however use +1 for the -1 uC charges because they add to the electric potential right?
