Three charges are arranged as shown in the diagram below. Their magnitudes are:
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)

Calculate the direction and magnitude of the force acting on q1.
Fe = kq1q2/r2
The Attempt at a Solution
F(q1q2)= 2.7x10^-23N [Equation above]
F(q1q3)=8.75x10^-23 [Equation above]
I used polar... trig. Do I have to show my work D:? Its hell on text.
The answer i obtained was 1.1x10^-22 N [Up 12 degrees Left] Could someone verify?
