Question 1 ++++++++ A hollow sphere has a uniform volume charge density of 4.04 nC/ms. The inner radius is a = 17.3 cm and the outer radius is b = 34.6 cm. What is the magnitude of the electric eld at 79.6 cm from the center of the sphere? Question 2 A charge of uniform linear density 2.24 nC/m is distributed along a long, thin, nonconducting rod. The rod is coaxial with a long conducting cylindrical shell with an inner radius of 5.71 cm and an outer radius of 10.8 cm. What is the surface charge density on the inner surface of the shell
