Explanation / Answer
Part B : Asteroids X, Y and Z have equal mass of 5 kg each. They orbit around a planet with M = 7.20 x 1024 kg. The orbits are in a plane of the paper and are drawn to scale.
In the statements below, TE is the total mechanical energy, KE is the kinetic energy, and PE is the potential energy.
(i) The KE of Z at m is Equal to that at s.
(ii) The PE of X at m is Greater than the PE of Z at s.
(iii) The TE of Y is Less than the TE of X.
(Because, it's semi-major axis is smaller)
(iv) The TE of Y is Equal to the TE of Z.
(Since, their semi-major axis are approximately equal)
(v) The PE of X at m is Less than that at a.
(vi) The PE of X at u is Greater than the PE of Y at s.
(Because, u is farther out than s)
(vii) The speed of X at u is Equal to that at m.
(viii) The PE of Y at s is Less than the PE of Z at s.
