(a) A small plastic bead with a charge of −60.0 nC is at the center of an insulating rubber spherical shell with an inner radius of 20.0 cm and an outer radius of 27.0 cm. The rubber material of the spherical shell is charged, with a uniform volume charge density of −1.30 μC/m3. A proton moves in a circular orbit just outside the spherical shell. What is the speed of the proton (in m/s )? m/s (b) What If? Suppose the spherical shell carries a positive charge density instead. What is the maximum value the charge density (in μC/m3 ) the spherical shell can have below which a proton can orbit the spherical shell? μC/m3

After the Sun exhausts its nuclear fuel, its ultimate fate will be to collapse to a white dwarf state. In this state, it would have approximately the same mass as it has now, but its radius would be equal to the radius of the Earth. (a) Calculate the average density of the white dwarf (in kg/m3). kg/m3 (b) Calculate the surface free-fall acceleration (in m/s2 ). m/s2 (c) Calculate the gravitational potential energy (in J) associated with a 1.82 kg object at the surface of the white dwarf. J (d) What If? The escape speed from the "surface" of the Sun, or a distance equal to its radius, is 617.5 km/s. What would be the escape speed (in km/s ) from the surface of the white dwarf? km/s

A hanging weight, with a mass of m1 = 0.360 kg, is attached by a string to a block with mass m2 = 0.850 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of vi = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. (a) Using energy methods, find the speed of the block (in m/s ) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance? rad/s
