A planet has a gravitational acceleration on its surface of 0.5 times Earth's gravitational acceleration on its surface. The planet's radius is two times Earth's radius. What is the mass of the planet, in terms of Earth masses, ME? Hint: Write equations for the gravitational acceleration on the surface of the planet and on Earth's surface in terms of their respective masses and radii. Then write the relationships between Earth's and the planet's gravitational accelerations, and between the Earth's and...

4. The equation mgy for gravitational potential energy is valid only for objects near the surface of a planet. Consider two very large objects of mass m1 and m2, such as stars or planets, whose centers are separated by the large distance r. These two large objects exert gravitational forces on each other.The gravitational potential energy is U = − Gm1m2 r where G = 6.67 × 10−11Nm2/kg2 is the gravitational constant. (a) Sketch a graph of U versus r....
