## Homework Statement

Take a look at this image first

If two electrons are each 2.50×10−10 from a proton, as shown in the figure, find the magnitude and of the net electrical force they will exert on the proton.

## Homework Equations

## The Attempt at a Solution

k=1/4πε0

So what I did first was calculate the Electric Force in the x directon

Fx= (k*q^2/r^2)cos(theta)

Fy=( k*q^2/r^2)sin(theta)

Then took the magnitude of the sum √(x)^2+(y)^2

And thought that would give me the answer for part one, where did I go wrong?
