A hollow non-conducting spherical shell has inner radius R1 =9 cm and outer radius R2 = 15 cm
Problem 8: A hollow non-conducting spherical shell has inner radius R1 =9 cm and outer radius R2 = 15 cm. A charge Q = -35 nC lies at the center of the shell. The shell carries a spherically symmetric charge density Q = Ar for R1 < r < R2 that increases
linearly with radius, where A = 16 μC/m4.
Part (a) Write an equation for the radial electric field in the region r < Ry in terms of Q, r, and Coulomb's constant k. You may take the positive direction as outward.
Part (b) What is the radial electric field at the point r = 0.5R? Given your answer in units of kN/C, and take the positive direction outwards.
Part (c) What is the radial electric field at the point r = 0.5(R1+R2)? Give your answer in units of kN/C.
Part (d) What is the radial electric field at the point r = 2R2? Give your answer in units of kN/C.
