In Fig. 23-52, a nonconducting spherical shell of inner radius 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 = 45.7 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?
