4. Another planet has four times the Earth's mass and two times the Earth's radius. If an object weighs 100 N on this planet, then what will the object weigh on Earth? 5. A person weighs 400 N on the Earth. What will this person weigh on a planet that has four times the Earth's radius and eight times the Earth's mass? 6. The Moon orbits the Earth with a period of about 27.3 days. How long will it take a satellite to orbit the Earth if its distance from the Earth is half the Moon's distance from the Earth? 7. An object weights 1000 N on planet Alpha. Planet Alpha has 15 times the mass of planet Beta and 2 times the radius of planet Beta. What will the object weight on planet Beta?
