If the gravitational force between two objects of mass M and m, separated by a distancer, has magnitude GMm where G = 6.67 × 10¬|" m’kg¯'s¯2, then the work required to increase the separation from a distance r¡ to a distance r2 is GMm(r,' – r,"). Compute the work required to move a 1500-kg satellite from an orbit 1000 km above the surface of Earth to an orbit 1500 km above the surface of Earth. Assume that Earth is a sphere of radius R. = 6.37 × 10° m and mass M. = 5.98 × 1024 kg. Treat the satellite as a point mass. (Write your answer in scientific notation with two decimal places.) 1.47 x10" J W = Incorrect
