Two satellite of earth, S 1 and S 2 are moving in the same orbit. The mass of S 1 is four times the mass of S 2 . Which one of the following statements is true:
Text Solution
Verified by ExpertsC
In same orbit, orbital speed of satellites remains same.
When two satellites of earth are moving in same orbit, then time period of both are equal.
From Kepler's third law T 2 ∝ r 3
Time period is independent of mass, hence their time periods will be equal.
The potential energy and kinetic energy are mass dependent, hence the PE and KE of satellites are not equal
But, if they are orbiting in a same orbit, then they have equal orbital speed.
