q1 = +2.5 x 10^-17 C

q2 = +3.0 x 10^-17 C

q3 = +3.5 x 10^-17 C

(its a right angle triangle, with 50 cm as the hypotenuse, 40 cm as the horizontal, and 30 cm as the vertical) sorry i don't have the actual triangle.

Calculate the direction and magnitude of the force acting on q1.

Relevant Equations:

Fe = kq1q2/r2

I'm not sure where to start. I believe I need to acquire all of the forces of q2, and q3 and then use Pythagoras theorem to find q1. Not sure if that's correct though
