How the layers change towards earth's centre
NettetConsider a satellite of mass m in a circular orbit about Earth at distance r from the center of Earth (Figure 13.12). It has centripetal acceleration directed toward the center of Earth. Earth’s gravity is the only force acting, so Newton’s second law gives. ... We need only replace M E M E with M Sun M Sun in Equation 13.8.
