A negative charge is placed between a pair of oppositely charged plates, as shown. Two horizontal parallel plates have a negatively charged sphere labeled X right in between them. The top plate is positive and the bottom plate is negative. Which best describes the result of moving the charge to the point marked X? Its electric potential energy increases because it has the same electric field. Its electric potential energy increases because the electric field increases. Its electric potential energy stays the same because the electric field increases. Its electric potential energy stays the same because it has the same electric potential.

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.
