(numbers 38-40) An ideal parallel plate capacitor with a dielectric material between the plates is charged by connecting it to a battery. The battery remains attached while the dielectric is now removed. During this removal of the dielectric:

38. The charge on the capacitor __________. a) increases b) decreases c) remains the same d) more information is needed to determine

39. The energy stored in the capacitor __________. a) increases b) decreases c) remains the same d) more information is needed to determine

40. Now that the capacitor has had the dielectric material removed, the capacitor plates are moved closer together, again with the battery remaining attached. During this process the magnitude of electric field between the plates __________. a) increases b) decreases c) remains the same d) more information is needed to determine

Pelase explain why and show formuals. Thank you.
