A capacitor consists of two 5.0-cm-diameter circular plates separated by 1.0 mm. The plates are charged to 160 V, then the battery is removed. (0 = 8.85 × 10^-12 C²/N-m²) Part A How much energy is stored in the capacitor? (Express your answer in joules to two significant figures.) Part B How much work must be done to pull the plates apart to where the distance between them is 2.0 mm? (Express your answer in joules to two significant figures.)
