Consider a hollow metal sphere of inner radius r=16.5 cm and outer radius R-20.5 cm. The sphere is not charged, but there is a point charge of q-253 nC at the centre of the sphere (a) Calculate the charge density on the sphere's outer surface (b) Calculate the electric field strength at the sphere's outer surface. PAPER SOLUTION Solve the problem on paper first, including all four IDEA steps. You will become a better physicist that way! Have you finished...
1-60 A hollow spherical iron container with outer diameter 20 cm and thickness 0.2 cm is filled with iced water at 0°C. If the outer surface temperature is 5°C, determine the approximate rate of heat loss from the sphere, in kW, and the rate at which ice melts in the container. The heat of fusion of water is 333.7 kJ/kg. Iced water 0.2 cm FIGURE P1-60
A 21.0 g copper ring at 0°C has an inner diameter of D = 2.50458 cm. A hollow aluminum sphere at 91.0°C has a diameter of d = 2.50922 cm. The sphere is placed on top of the ring (see the figure), and the two are allowed to come to thermal equilibrium, with no heat lost to the surroundings. The sphere just passes through the ring at the equilibrium temperature. What is the mass of the sphere? The linear expansion...

A hollow aluminum sphere, with an electrical heater in the center, is used in tests to determine the thermal conductivity of Insulating materials. The inner and outer radii of the sphere are 0.15 and 0.18 m, respectively, and testing is done under steady-state conditions with the inner surface of the aluminum maintained at 250°C. In a particular test, a spherical shell of Insulation is cast on the outer surface of the sphere to a thickness of 0.12 m. The system...
