2. A nonconducting hollow sphere of inner radius 0.030 m and outer radius 0.050 m carries a positive volume
charge density p, as shown in the figure above. The charge density p of the sphere is given as a function of the
distance r from the center of the sphere, in meters, by the following.
r< 0.030 m: p = 0
0.030 m <r< 0.050 m: p = b/r, where b = 1.6 × 10 C/m?
r>0.050 m: p = 0
(a) Calculate the total charge of the sphere.
(b) Using Gauss's law, calculate the magnitude of the electric field E at the outer surface of the sphere.
(c) On the axes below, sketch the magnitude of the electric field E as a function of distance r from the center
of the sphere.
