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

Three point charges are located at the corners of an equilateral triangle with side length a=0.50m

2. Relevant equations

3. The attempt at a solution

My question is how can I subtract the vector F_{2/1}? Vectors cant be negative right? I found the magnitude of the vector to be negative. Should I have not included the negative sign for the 4 micro coulomb charge? Then I add the two vectors and that will give me the correct result.

My result is correct, but I cant minus vectors so I kind of did it illegally ya?

Thanks for your help.
