1. In Griffiths Problem 2.14, we considered a sphere of radius $R$ that carries a volume charge density \(\rho = kr\), where $k$ is constant and $r$ is the distance from the sphere's center. Find the electric field outside the sphere.

Step 1
First, we need to determine the charge enclosed within a sphere of radius r, where r > R (the radius of the given sphere). To do this, we can integrate the volume charge density over the volume of the smaller sphere. The volume charge density is given as ρ = kr, Show more…

Solid Nonconducting Sphere A solid nonconducting sphere of radius $R$ has a nonuniform charge distribution of volume charge density $\rho=\rho_{s} r / R$, where $\rho_{s}$ is a constant and $r$ is the distance from the center of the sphere. Show (a) that the total charge on the sphere is $Q=\pi \rho_{s} R^{3}$ and $(b)$ that $$ |\vec{E}|=k \frac{|Q|}{R^{4}} r^{2} $$ gives the magnitude of the electric field inside the sphere.
The charge density within a charged sphere of radius $R$ is given by $\rho=\rho_{0}-a r^{2},$ where $\rho_{0}$ and $a$ are constants and $r$ is the distance from the center. Find an expression for $a$ such that the electric field outside the sphere is zero.
Find the electric field inside a sphere which carries a charge density proportional to the distance from the origin, $\rho=k r,$ for some constant $k$. [Hint: This charge density is not uniform, and you must integrate to get the enclosed charge.]
