Quizplus · Accepted Answer

This is due to the fact that the force of gravitational attraction is always equal in magnitude but opposite in direction for two objects. So, if Joshua is attracted towards the Earth with a force of 500 N, then the Earth is also attracted towards Joshua with an equal but opposite force of 500 N. Therefore, the correct answer is (C) 500 N.
