If a planet has 3 times the radius of the Earth,but has the same density as the Earth,what is the gravitational acceleration at the surface of the planet? (g = 9.8 m/s²) A) 29.4 m/s² B) 88.2 m/s² C) 265 m/s² D) 3.27 m/s²

Quizplus · Accepted Answer

The gravitational acceleration at the surface of a planet is proportional to its radius if the density is constant. Since the planet's radius is 3 times that of Earth, the gravitational acceleration will be 3 times that of Earth, which is 3 * 9.8 m/s² = 29.4 m/s².
