Is it possible for the electric field between two positive charges to equal zero along the line joining the two charges? is it possible for the electric field between two positive charges to equal zero along the line joining the two charges? yes, but only if the two charges are equal in magnitude. yes, regardless of the magnitude of the two charges. no, a zero electric field cannot exist between the two charges. this cannot be determined without knowing the separation between the two charges?

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.
