Problem 84P

Use the charge distribution and electric field calculated (a) Show that for ?r ? ?R the potential is identical to that produced by a point charge ?Q?. (Take the potential to be zero at infinity.) (b) Obtain an expression for the electric potential valid in the region ?r? ? ?R?. Problem: A nonuniform, but spherically symmetric, distribution of charge has a charge density ? ?? ?) given as follows: Where ??0 = 3?Q?/??R?3 is a positive constant. (a) Show that the total charge contained in the charge distribution is ?Q?. (b) Show that the electric field in the region ?r ? ?R is identical to that produced by a point charge ?Q at ?r = 0. (c) Obtain an expression for the electric field in the region ?r ? ?R?. (d) Graph the electric-field magnitude ?E as a function of ?r?. (e) Find the value of ?r at which the electric field is maximum, and find the value of that maximum field.
