(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

three spheres, each with a negative charge of 4.0 X 10^-6 C, are at the vertices of an equilateral triangle whose sides are 0.20m long. Calculate the magnitude and direction of the net electric force on each sphere.

2. Relevant equations

Fe= kq1q2/r^2, where k is the constant, k=9.0 X 10^9 N*m^2/C^2

3. The attempt at a solution

i plugged in the values..but I don't seem to be getting the answer. There are 2 forces acting on each of the spheres, right? the answer is 6.2N
