5. Homework for next class -
   
   The following charge distribution applies as a rough model of
   
   the charge inside a light atomic nucleus, say a calcium nucleus
   
   (Ca,atomic number 20).
   
   A spherical charge distribution is given by

(a) Calculate the total charge inside the sphere of radius a.

(b) Find the electric field vectors outside the nucleus, say at a

distance r = 2*a

(c)Compute the flux (surface) integral of the electric field over

the sphere of radius 2*a.

(d)Compare your results from parts (a) and (c) with Gauss's

Law. Is Gauss's Law verified?
