# Problem: Three point charges are arranged at the corners of a square of side L as shown in (Figure 1) What is the potential at the fourth corner (point A)? Express your answer in terms of the variables Q, L, and the Coulomb's constant k.

###### FREE Expert Solution

Potential:

$\overline{){\mathbf{V}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{Q}}{\mathbf{d}}}$

At point A, the potential will be:

VA = V-2Q + V+Q + V+3Q
