1. The problem statement, all variables and given/known data
Two spheres, each radius R and carrying uniform charge densities +rho and -rho are placed so that they partially overlap. Call the vector from the positive center to the negative center dhat. Show that the field in the region of overlap is constant and find its value.
2. Relevant equations
3. The attempt at a solution
So I did Gauss' law for one sphere to find e-field. What I got was
So the e-field from the positive sphere is E=(rho*r)/(3*episolon)
e-field from negative is the opposite of course.
principle of super position, don't they add up to zero?
