Express your answer with the appropriate units.   B - What is the total charge on the inside surface of the hollow sphere? Express your answer with the appropriate units.   C - What is the total charge on the exterior surface of the hollow sphere? Express your answer with the appropriate units.

(c) Calculate the magnitude q of the charge on the left circular face of the foil. You may need to make simplifying assumptions or approximations. Hint: look at your diagram of the foil disk, when considering how to model the charge on the foil.

The figure shows a solid non-conducting sphere of radius a = 4.4 cm. It is surrounded by a charged conducting spherical shell of inner radius b = 15.3 cm and outer radius c = 24.8 cm. The inner sphere has a net charge of q1 = 9 nC and the conducting spherical shell has a net charge of q2 = -7 nC.   a. What is the surface charge density on the inside surface of the spherical shell? b. What is the surface charge density on the outside surface of the spherical shell? c. What is the value of the electric field at a distance r = 58 cm from the centre of the spheres? Please use a negative value to indicate the electric field points toward the centre of the spheres and a positive value to indicate away from the centre of the spheres.

There could be charge on C, but there is no 1. net charge on C. 2. There cannot be charge on C. There could be charge on C and there is net 3. charge on C. C A metal block containing a cavity and car- rying a net charge –Q is located near a pos- itive charge +q_as shown in the figure. In static equilibrium, can there be any charges on the inner surface C of the cavity?
