A parallel plate capacitor of capacitance 4.3 µF has the space among the plates filled with a slab of glass with = 3.6. The capacitor is charged by attaching it to a 1.6-V battery. After the capacitor is disconnected from the battery, the dielectric slab is removed.
1. Discover the capacitance after the glass is removed.
2. Discover the potential difference after the glass is removed.
3. Discover the charge on the plates after the glass is removed.
4. Discover the energy stored in the capacitor after the glass is removed.
