Question:-
A satellite in a circular orbit of radius R has a period of 4 hours. Another satellite with orbital radius 3R around the, same planet will have a period (in hours)
Given:-
We know that Kepler's Third law states that, The square of it's period of revolution around Sun is directly proportional to cube of mean distance of a planet from the Sun. Then,
Thus, we get,
Thus, Period of second satellite will be:
Thus,
The same planet will have a period of 4 √27 hours.
