8. Centripetal Forces & Gravitation / Acceleration Due to Gravity / Problem 8
Suppose there is a planet with a mass that is 4 times the mass of the Earth. If a spaceship lands on the planet's surface, it measures the free-fall acceleration to be 1/8 of that of the Earth's acceleration due to gravity. Determine the radius of the planet.
