An isolated parallel-plate capacitor (not connected to a battery) has a charge of Q = 1.7×10−5C. The separation between the plates initially is d = 1.2 mm, and for this separation the capacitance is 3.1×10−11F. Calculate the work that must be done to pull the plates apart until their separation becomes 2.6 mm, if the charge on the plates remains constant. The capacitor plates are in a vacuum. Express your answer using two significant figures. (unit in J)

A parallel plate capacitor with plate separation of 1 millimeter is connected to a battery of 10 volts. If the region between the plates is free space (epsilon_r = 1), calculate the electric field between the plates in Volts/meter, and the electric flux density between the plates in Coulombs/m^2. Suppose a dielectric with dielectric constant epsilon_r = 5 is inserted between the plates. With the battery still connected, calculate the electric field and the electric flux density. Which field has...
