In the figure a nonconducting spherical shell of inner radius a = 2.33 cm and outer radius b = 2.42 cm has (within its thickness) a positive volume charge density p = A/r, where A is a constant and ris 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? Number i 4.36E-11 Units C/m^2
