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 inner and outer conductive metal shells. Two dielectrics of absolute permittivity 1 and 2 fill the regions between the shells. A positive charge ( Q) is distributed on the inner metal shell, and a negative charge (-Q) on the outer metal shell. Spherical capacitor 4 2.1.1 Provide a symbolic expression for the electric field intensity, E1 (as a function of r, E=E(r)), in the region R1< r < R2. Note: aside from standard mathematical constants and symbols (e.g. ), use only symbols shown in the figure and provided in the problem statement
