Find the magnitude and direction of the net electric field at the centre (or centroid) of the triangle.(adsbygoogle = window.adsbygoogle || []).push({});

The triangle is equilateral and the point of reference is in the middle of the triangle.

What I want to know is what equation do I use to figure this out?

At first I thought it was: Fnet = kq1q2/r^2

Is that right?, if not can you tell what to use?
