Consider a charged metallic spherical shell of radius a = 1.75 cm. The potential at a distance of r = 6.0 cm from the center of the shell is measured to be 1.5kV. What is the charge on the shell? Calculate the potential on the surface of the shell. (Note: V = kQ/r. You may also like to read the chapter of your textbook that discusses the Electrostatic Potential.)
