A sphere with radius a = 8 cm is in a conductive sphere shellwith an internal radius of b = 12 cm and an outer radius of c = 18cm with a load of -200 mC.
a) Determine the load distribution in the sphere and sphereshell.
b) Calculate the value of the electric field in r = 0 cm, r = 4 cm,r = 8 cm, r = 10 cm, r = 14 cm, r = 18 cm and r = 50 cm, and plotthe electric field with respect to r.
