A planet has a mass of M1, a radius of R1, and a density of Q1 A second planet has a mass of M2, a radius of R2, and a density of g2. This problem will explore the relationships between the surface gravities (g1 and g2) of the planets depending on the relative sizes of their masses, radii, and densities. Assume that planet 2 has X times the mass of planet 1, or M2 - XM1. The densities of both...

Assume a planet is a uniform sphere of radius R that (somehow) has a narrow radial tunnel through its center. Also assume we can position an apple anywhere along the tunnel or outside the sphere. Let FR be the magnitude of the gravitational force on the apple when it is located at the planet's surface. How far from the surface (what multiple of R) is there a point where the magnitude of the gravitational force on the apple is 0.3...

In Year 3,000 humans mastered to forge a new planet from materials collected in the asteroid belt between Mars and Jupiter. This new planet F has radius RF=48,000 km. If an object is placed at an altitude h =5,200 km above the surface of Planet F, the object’s weight is the same as on the surface of the Earth. What is the gravitational acceleration gFs on the surface of Planet F in m/s2? (Hint: Eliminate the mass of Planet F...
