Quizplus · Accepted Answer

The force of gravity between two objects is directly proportional to their masses and inversely proportional to the distance between them squared. In this scenario, since rock S has 20 times the mass of rock T, it will exert a greater gravitational force on rock T than vice versa. Therefore, rock T will accelerate more towards rock S and move faster towards it.
