A point charge, q=−4.75 pC, is placed at the center of a spherical conducting shell of inner radius 3.1 cm and outer radius 4.1 cm. The electric field just beyond the outer surface of the conducting shell is directed radially outward and has magnitude 6.6 N/C. Part (a)
Part (b)
What is the charge density, in coulombs per squared meter, on the outer surface of the conducting shell?
What is the charge density, in coulombs per squared meter, on the inner surface of the conducting shell?
