just need bottom two question answered.

A point charge, \( q \), is at the center of a sphere of dielectric material. The sphere has a radius \( a \) and dielectric constant, \( \varepsilon_r \). The sphere of dielectric material is surrounded by a thick neutral conducting shell with inner radius \( a \) and outer radius \( b \). 1. Determine the electric field in each region. 2. Determine the bound charge densities, both \( \sigma_b \) and \( \rho_b \), for the dielectric sphere. 3. What is the total bound charge on the surface of the dielectric sphere? Since the total bound charge for a dielectric must be zero, where is the compensating (opposite sign) bound charge located? 4. Calculate the energy stored in this system. **Diagram Explanation:** The diagram shows a cross-section of the described system: - A central point charge \( q \) is surrounded by a shaded sphere representing the dielectric material. - The dielectric sphere has a radius \( a \). - Encircling this sphere is a larger neutral conducting shell, not shaded, with an inner radius \( a \) and an outer radius \( b \).
