In the figure a nonconducting spherical shell of inner radius a = 2.05 cm and outer radius b = 2.56 cm has (within its thickness) a positive volume charge density ρ = A/r, where A is a constant and r is the distance from the center of the shell. In addition, a small ball of charge q = 48.0 fC is located at that center. What value should A have if the electric field in the shell (a ≤ r ≤ b) is to be uniform? Number Units

Q5 (5 pts) Electrical charge is distributed uniformly with volume charge density ρ inside a spherical shell of inner radius a and outer radius b. There is a positive point charge Q located at the center. Electric field inside the shell is given by E→ = Cr where C is a positive constant r is the radial distance from the center. (a) Calculate ρ of the spherical shell. (b) Calculate the E field for r > b.

A nonconducting spherical shell, with an inner radius of 4.2 cm and an outer radius of 7.6 cm, has charge spread nonuniformly through its volume between its inner and outer surfaces. The volume charge density ρ is the charge per unit volume, with the unit coulomb per cubic meter. For this shell ρ = b/r, where r is the distance in meters from the center of the shell and b = 5.7 μC/m2. What is the net charge in the shell?
