Three charges reside on an equilateral triangle with sides equal to d. All three charges are equal in magnitude and sign.(adsbygoogle = window.adsbygoogle || []).push({});

What is the magnitude of the force F' on one of the three charges q due to the total electric field from the other two charges q on the corners of the equilateral triangle?

Okay, so this problem is driving me nuts because I cannot get the correct solution, which by the way is 1407 Newtons. q=60 micro C and d=20 cm.

I tried to find the force of the one charge due to other two charges by using coulomb's law, and the direction, but I couldn't seem to get it. Any help is greatly appreciated.
