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

A proton and an electron form two corners of an equilateral triangle of side length 5.3 x 10-6 m. What is the magnitude of the net electric field these particles produce at the third corner?

2. Relevant equations

E=kQ/r^2

3. The attempt at a solution

I drew a triangle with an electron and a proton as the corners. I'm thinking of using Pythagorean theorem or something then solve this with the formula by dividing the distance. I'm sort of confused but i do know that the answer will be negative.
