1. The problem statement, all variables and given/known data
Two identical point charges, q1 = +2.5 x 10-6 C and q2 = +2.5 x 10-6 C, are placed as shown in the diagram below. Point P is a distance 0.05 m from q1 and 0.12 m from q2, such that the angle at P is 90 degrees. Calculate the magnitude of the Electric field E at point P.

2. Relevant equations
Not sure which of these rules would apply.
F = k x q1 x q2 / r^2
E = F / q
E = k x Q / r^2
F = k x I1 x I2 x L / d
3. The attempt at a solution
So I have created the diagram and I believe I have to use the third formula twice, along with some trigonometry, but I'm not sure.
