Part 1
The goal of these problems is to use Gauss' law to explore relationships between electrostatic charge, electric field intensity, electric flux density, and energy storage in an atypical capacitor. Consider a spherical capacitor with two hemispherical dielectrics of absolute permittivity ei and E2. A positive charge (+Q) is distributed on the inner metal shell, and a negative charge (-Q) on the outer metal shell.
