Apoint charge q 6.5 x 10 12 c is placed at the center of a spherical conducting sh ell of surface of the conductor is directed radially outward and has magnitude 7.5 n/c. ner radius 3.7 cm and outer radius 4 6 cr ti e elect field use above the (a) what is the charge density (in c/m2) on the inner surface of the shell? (b) what is the charge density (in c/m2) on the outer surface of the shell? c/m2 (c) what is the net charge (in c) on the conductor?
