How to solve part 2 of this question? I have an answer of 1.97E22 for part A but I am having trouble with part B. A. The Earth has a mass of 5.97 * 1024 kg and the Moon has a mass of 7.35 * 1022 kg. If they are separated by a distance of 3.85 * 105 km, what is the force (in N) between the Earth and the Moon? (Enter your answer in scientific notation: 1.23E12 means 1.23 * 1012) B. Repeat the previous problem using centripetal forces. Assume the Moon travels in a perfect circle around the Earth, with masses and distances given above, and takes 27.32 days to complete a complete circle. What is the centripetal force (in N) acting on the Moon? (Think about why and by how much the answers to these two questions differ.)
