Repeat Question 20 if the capacitor is charged and then disconnected from the battery before removing the dielectric slab.
In questions 20
A parallel plate capacitor has the space between the plates filled with a slab of dielectric with k = 3. While the capacitor is connected to a battery, the dielectric slab is removed. Describe quantitatively what happens to the capacitance, the potential difference, the charge on the plates, the electric field, and the energy stored in the capacitor as the slab is removed.
