In the figure a nonconducting spherical shell of inner radius a- 2.23 cm and outer radius b-2.52 cm has (within its thickness) a positive volume charge density p - Air, where A is a constant and r is the distance from the center of the shell. In addition, a small ball of charge q- 48.4 fC is located at that center. What value should A have if the electric field in the shell (a srsb) is to be uniform?
