1. A spherical capacitor that consists of an inner conducting sphere with a radius R1 surroundedby a concentric conducting spherical shell with an inner radius R2 and an outer radius R3(Fig. 2). Assuming the system is floating (i.e. not grounded) with no net charge. Thepotentials at the surface with R1, R2 and R3 are O1, D2, and D3, and the charges at the surfacewith R1, R2 and R3 are Q1, Q2, and Q3(a) determine the relationship between O1, 02, and O3 and the relationship between Q1, Q2,and Q3,(b) calculate the capacitance.RFig. 2

Problem 5 Consider a parallel-plate capacitor with a plate area of A = 8.50 cm². The separation between the plates is d₂ = 3.00 mm (the space between the plates is filled with air). The plates of the capacitor are charged by a 6.00 V battery, i.e., the potential difference between the plates is V₂ = 6.00 V. The plates are then disconnected from the battery and pulled apart (without discharge) to a sepa- ration of df = 8.00 mm. In the following, neglecting any fringing effects. (a) Will the new potential difference between the plates be larger, smaller, or the same compared to the initial potential difference of V₂ = 6.00 V? Explain. (Hint: Note that the charge will not change when the plates are pulled apart. Why is that?) (b) Find the potential difference Vf between the plates after the plates have been pulled to their new, larger separation df. (c) Find the electrostatic energy stored in the capacitor before and after the plates are pulled apart. (d) To separate the plates, you will…
