# Magnitude of Electric field at point P

## Homework Statement

If Q=80nC, a=3.0m , and b=4.0m in the figure, what is the magnitude of the electric field at point P?

EF=k*Q1*Q2 / R^2

## The Attempt at a Solution

I'm not sure how to go about solving this problem. Do I use the above equation? I don't have the answer to the problem so I'm kinda in the dark about this. Thanks.
