A: What is the capacitance of a thin parallel-plate capacitor (with plate area A, and plate separation d) if it is half full of an insulating material with dielectric constant K? Hint: consider this as two capacitors connected in parallel. B: If the capacitor has charge +Q and -Q on the two plates, how much work does one have to do on the dielectric to completely remove the dielectric from the capacitor? You can neglect other forces than the electric force. C: If the capacitor has charge +Q and -Q on the two plates, and the dielectric block is halfway inserted, is there a force on the block, and if so, which way and how large?
