A circular ring of charge of radius b has a total charge q uniformly distributed around it. The electric field at the center of the ring is a. 0 12. A solid spherical conductor has charge+Q. A particle with charge +q is placed at the center of a cavity located in the sphere. The charge on the surface of the cavity and the charge on the outer surface of the sphere, respectively are c. Q,0 --13. A charge of 8 X10-12 C is spread uniformly over the a spherical shell of radius 2 cm. Determine the electric field 3 cm from the center of the sphere. a. 90 N/C b. 30 N/C c. 80 N/C d. 40 N/ 14. The electric field inside a spherically symmetric shell of radius R and charge Q is b. kQ/r c. kQ/r a. zero 15. A point particle with charge q is at the center of a Gausssian surface in the form of a cube. The total flux in N m'/C through all sides of the cube is a. 0 c. q/38o d. q/66
