Two identical capacitors (A and B) with capacitance Co are hooked up to a battery of voltage Vo. A dielectric of constant ko is added between the plates of capacitor B while it is connected to the battery, as in the figure at right. a) Is the charge on capacitor A (QA) greater than, less than, or equal to the charge on capacitor B (QB)? What about the voltages (VA and VB)? Explain your reasoning. b) Vo CB The capacitors above are carefully disconnected from the battery (without being discharged), after the battery is disconnected the dielectric slab is removed from capacitor B. The capacitors remain connected to each other the entire time. Determine an expression for the final charges on each of the capacitors (QA₁f and QB₁f) after the dielectric has been removed in terms of the given constants (Ko, Co, Vo).

A spherical capacitor consists of an inner spherical shell of radius R1 and an outer spherical shell of radius R2, as shown above. Our goal is to calculate the capacitance of this configuration of electrodes.To start, suppose the inner sphere has a charge +Q and the outer sphere an equal but opposite charge -Q. Find the capacitance using the following steps:1. Use Gauss's law to find an expression for the electric field in the region between the two spheres.2. Find an expression for the potential difference between the spheres from the electric field (you'll have to integrate the electric field from the negative electrode to the positive one).3. Calculate the capacitance from C = Q / ΔV.Suppose in this case that R1 = 2.00 cm and R2 = 4.30 cm. What is the value of the capacitance?
