Part B If the gravitational potential energy is zero at the surface, what is the potential energy for a 35 kg fragment at its maximum height (500 km) on lo? Express your answer in joules. AEQ ? U = J Submit Request Answer 4 Part C How much would this gravitational potential energy be if it were at the same height (500 km) above earth? Express your answer in joules. ? U = Submit Previous Answers Request Answerlo, a satellite of Jupiter, is the most volcanically active moon or planet in the solar system. It has volcanoes that send plumes of matter over 500 km high. Due to the satellite's small mass, the acceleration due to gravity on Io is only 1.81 111/52, and lo has no appreciable atmosphere. Assume that there is no variation in gravity over the distance traveled
