Coulomb’s Forces

1. The problem statement, all variables and given/known data

Consider the triangle of charges diagrammed below, for which d = 5 cm, q = 2 nC, and the +x-axis points to the right. What is the force Fvec on the 1 nC charge? Give your answer as a magnitude and a direction.

2. Relevant equations

F=K(q)(Q)/r^2

3. The attempt at a solution

I am not sure what to do. I converted the nc to c, and the cm to m. Then I did

F= K(1X10^-9)(2X10^-9)/.05^2

Then I would multiply this by two because the two sides are effecting the charge. Is this on the right track?

Thanks
