AP Physics Exam questions and answers Graded A+

AP Physics Exam questions and answers Graded A+ Planet X has a mass of MM and a radius of RR. Planet Y has a mass of 3M3M and a radius of 3R3R. Identical satellites orbit both planets at a distance RR above their surfaces, as shown above. The planets are separated by such a large distance that the gravitational forces between them are negligible. How does the magnitude of the gravitational force FYFY exerted by Planet Y on its satellite compare to the gravitational force FXFX exerted by Planet X on its satellite? - ☑ ☑ FY=3/4FX Planet X has a mass of MM and a radius of RR. Planet Y has a mass of 3M3M and a radius of 3R3R. Identical satellites orbit both planets at a distance RR above their surfaces, as shown above. The planets are separated by such a large distance that the gravitational forces between them are negligible. How does the gravitational field gXgX at the surface of Planet X compare with the gravitational field gYgY at the surface of Planet Y? - ☑ ☑ gX=3gY A moon orbits a planet in a nearly circular or
