1. The problem statement, all variables and given/known data Hi guys! If I have two positive charges really close to each other, what would be the electric stress between the positive charges? Now I don't need a numerical answer, but I would like to know if my attempt is correct. 2. Relevant equations σ=ε(EiEj-(1/2)δij(E^2)) 3. The attempt at a solution I figured that I should add the electric fields between the two positive charges and then use that as E in the equation above to calculate the stress between them.
