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?
