Assume that these two radii are very close to each other so that the following are valid approximations. • Charge on each hemisphere is distributed uniformly over the surface of the hemisphere. • The electric field between the hemispheres is radial and its magnitude depends only on the radial coordinate r. • The electric field outside the hemispheres is negligible. Suppose that when the capacitor is charged, the charge on the inner hemisphere is Q and the charge on the outer hemisphere is –Q.
