Unformatted text preview: R , one conducting, one having a uniform charge density within its volume, and one having a spherically symmetric charge density that varies radially as r n ( n >-3), has a total charge Q . Use Gauss’s theorem to obtain the electric ﬁelds both inside and outside each sphere. Sketch the behavior of the ﬁelds as a function of radius for the ﬁrst two spheres, and for the third with n =-2 , +2. 4. Prove that the following charge distribution ρ = q n Y i =1 ( a i · ∇ ) δ ( r ) creates the potential φ ( r ) = q n Y i =1 ( a i · ∇ ) 1 r...
