1. The problem statement, all variables and given/known data
The diagram shows three charges, A (+5.0 μC),B (-7.0 μC), and C (+2.0 μC), placed at three corners of a rectangle. Point D is the fourth corner. What is the electric potential at point D?

2. Relevant equations
VEL = $\frac{(k)(q1)}{d}$

3. The attempt at a solution
I don't know how to find it at Point D.
