1. Homework Statement
Three point charges are located at the corner of an equilateral triangle. The Coulomb constant is 8.98755 X 109 N*m2 / C2
What is the strength of the electrostatic force on the top charge? Answer in units of N.

Length of each side is .19m

2. Homework Equations

F= [k(q1)(q2)] / r^2

3. The Attempt at a Solution

I know I must get F1 & F2, but then I don't know what to do

F1=[k(2.68E-6)(1.32E-6)] / .19^2 = .880730107

F2= [k(2.68E-6)(-3.93E-6)] / .19^2
