3. (8 points) Consider a conducting sphere with total electric charge +Q with radius Rị centered at p= 0 (spherical coordinates). The surface charge at r = R1 is spread uniformly on this spherical surface. There is also an outer conducting shell of radius r = R2, centered at r = 0 and with total electric charge - Q also spread uniformly on the surface. This arrangement of separated positive and negative charge forms a capacitor. We will assume that...
