In the figure shown, electrons 1 and 2 are on the x-axis while charges
3 and 4 are on the y-axis. The charges 3 and 4 are identical with
charge -Ne and at identical angle θ(theta). N is an integer. Electron 2 is
free to move while the other charges are fixed in place a horizontal
distance R from electron 2. Determine the angle as a function of
N so that electron 2 experiences no net force.
Here is a link to the image included with the problem.

I thought I would use the equation E=(k*q)/r² or use E=(k*Q*q)/r²
E=electric field
k=constant 8.99x10^9
q= the charge
Q= the other charge
r= radius
Even help with the first step will likely help so I can get on the right path. I'm not sure how to do this one at all. Just trying to study for a test on Friday and pulling out problems that I do not know how to do. Thank you in advance!
