3. Lecture 10: Consider a parallel plate capacitor with capacitance 14 μF. This capacitor is charged to a potential difference of 100 V between the two plates. (a) What is the amount of charge on the plates? (b) For this capacitor the space between the charged plates is filled with neoprene. We proceed to pull out the insulating material: what is the amount of charge on the plates after we pull out the neoprene sheet? (c) How much work did we have to do to pull out the dielectric material (assuming that we could do so without friction)? Hint: you may take EneopEvacuum for the permittivity of the dielectric.
