If the period of revolution of a nearest satellite around a planet of radius R is T then its period of revolution around another planet, having radius 3R and same density will be
A
T
B
3T
C
9T
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For a nearest satellite, the period of revolution is
i.e., the period of revolution depends upon the density of the planet. Here, the density of the planets is same, therefore time period will be same.
