## Homework Statement

A point charge of -7e-6 C is located at x = 3 m, y = -2 m. A second point charge of 12e-6 C is located at x = 1 m, y = 3 m.

## Homework Equations

## The Attempt at a Solution

Dq1 = sqrt(20)

Dq2 = sqrt (13)

E1 + E2= k(-7e-6)/20 + k(-7e-6)/20 = 11444.96 N/C

What am I doing wrong?

And how to find the direction ?
