Question

Two charged droplets of toner ink behave as two shells of uniform surface charge density. (Toner is an insulating material, not conductive.) The two drops have total charge qi, radiusRi, and centre positionri,i= 1,2. Assuming the drops do not overlap, derive the electric potential, V(r), everywhere inside and outside the spheres. Is the voltage (potential) inside shell 1 constant? In this last question, shouldn't we take into consideration the potential created by the other sphere?
