A 3.50 %u03BCC point charge is placed at the center of a conducting spherical shell. This conducting shell has an inner diameter of 10.0 cm and an outer diameter of 15.0 cm. The conducting shell is given a net charge of -2.50 %u03BCC.
What is the surface charge density (C/m2) on the outer surface of the conducting shell? (Hint: Use Gauss%u2019s Law to determine how much charge is on the inside surface of the conducting shell)
