Point charge in a conducting shell. A point charge +q is located inside a very thin conducting spherical shell halfway between the center and the shell shown in Figure 5.46. Assume the conducting shell is at zero potential.
(a) Calculate the electric field intensity at the center of the sphere.
(b) What is the field outside the sphere?
(c) Plot the electric field intensity inside the sphere by plotting the field lines (approximate plot is sufficient).
