Two concentric conducting spheres have radii of 3cm and 5cm. The region between them is filled with a homogeneous dielectric for which &, = 5. If the potential of the inner sphere is 100V while that of the outer is -100V, determine i) The potential function V(r) The electric field E ii) iii) iv) The potential midway between the spheres The value of r at which V = 0 v) The charge on the inner sphere vi) The capacitance between the two spheres.
