An astronaut named Alex is exploring a newly discovered planet, Xylon, which has a mass of 5 × 10²⁴ kg and a radius of 6,400 km. Alex, with a mass of 80 kg, is on the surface of Planet Xylon. The planet is unique because it has only one-sixth of the density of Earth but the same surface gravity.
In the relation F = G M m/d², the quantity G
The force of attraction between two unit point masses separated by a unit distance is called
Calculate the average density of the earth in terms of g, G and R.
