Question
I am having a hard time understanding why the solved answer on your site, for the following question, uses x-2 instead of x+2 for the -2q charge. I attached my work for part A as well as where I am confused at. Aren't I just supposed to solve for x at this point? The - seems to be throwing me off. Any explanation you can offer would be appreciated!
Expert Solution
Step 1
Given
From Coulomb's law, we know the electric field at a distance r form the point is given as
And electric potential at some point due to several point charge is the sum of individual potential
