(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

A long, straight wire with a circular cross section of radius R carries a current I. Assume that the current density is not constant across the cross section of the wire, but rather varies as J = αr, where α is a constant. Part A By the requirement that J integrated over the cross section of the wire gives the total current I, calculate the constant α in terms of I and R. Express your answer in terms of the variables I and R. Part B Use Ampere's law to calculate the magnetic field B(r) for r ≤ R. Express your answers in terms of I. Express your answer in terms of the variables I, R, r, and magnetic constant μ0. Submit Request Answer Part C Use Ampere's law to calculate the magnetic field B(r) for r ≥ R. Express your answers in terms of I. Express your answer in terms of the variables I, r, and magnetic constant μ0.A long, straight wire with a circular cross section of radius R carries a current I.
