A diagram shows a large central circle representing a planet of mass M. A dashed circular path with radius R surrounds the planet. A small square representing a satellite is positioned on the path at the top. A horizontal arrow labeled v points to the left, tangent to the path. A vertical arrow labeled Fg points from the satellite directly toward the center of the planet.
A satellite in a circular orbit around a planet of mass M.
A satellite of mass \(m\) is in a stable circular orbit of radius \(R\) around a planet of mass \(M\). The magnitude of the gravitational field strength produced by the planet at the satellite's location is \(g\). Which of the following correctly compares the magnitude of the satellite's centripetal acceleration \(a_c\) to \(g\), and provides a correct justification?
