5PRACTICE PROBLEM
Consider an imaginary planet having the shape of a uniform spherical shell in our Milkway galaxy. The planet's mass is 3.0 × 1021 kg and the shell radius is 100 km. Determine the gravitational force exerted by the planet on a 200 kg point-like alien situated at i) 101 km, ii) 99 km. and iii) 200 m from its center.
