What is the Universal law of gravitation equation?
A planet has a radius one-half that of Earth and a mass one-fifth the Earth’s mass. The gravitational acceleration
at the surface of the planet is most nearly to __________.
Two planets reside in the Trappist-1 planetary system. Trappist 1-C is a planet that has a mass 1.5 times greater than Earth’s mass, while Trappist 1-D has a mass that is half of the Earth’s mass. If Trappist 1-C has the same diameter as Earth, is the same distance away from its host star as is Earth is away from the sun, and its host star has the same mass as the sun, what would be the acceleration due to gravity on the surface of Trappist 1-C?
