A solid nonconducting sphere has a volume charge distribution given by $\rho(r)=(\beta / r) \sin (\pi r / 2 R) .$ Find the total charge contained in the spherical volume and the electric field in the regions $r<R$ and $r>R .$ Show that the two expressions for the electric field equal each other at $r=R$.
In the infinitely long cylindrical structure shown in Figure 3, the region r < a is filled with an electric charge density of ̑́̑(r) = ̑́̑₀(1 - r/a) Coul/m, where ̑́̑₀ is a constant. Concentric with this charge cloud, a cylindrical conducting shell is placed in Fig.3. The region r < a is occupied by vacuum, the region a < r < b is filled with dielectric, having permittivity ̑̐₁, and the region b < r < c is composed of a conductor. Use Gauss's Law (given charge distribution in charge cloud is symmetric): a) Determine the electric flux density D vector for every region given above. b) Determine the electric field intensity E vector for every region given above. Note that r represents ̑́̑ in the cylindrical system. Note that R is in spherical coordinate systems.

A charge cloud contained in a sphere $B$ of radius $r$ centimeters centered at the origin has its charge density given by $\quad q(x, y, z)=k \sqrt{x^{2}+y^{2}+z^{2}} \frac{\mu C}{\mathrm{cm}^{3}}, \quad$ where $ k > 0 .$ The total charge contained in $B$ is given by $Q=\iiint_{B} q(x, y, z) d V .$ Find the total charge $Q .$
