A satellite A of mass m is at a distance of r from the surface of the earth. Another satellite B of mass 2m is at a distance of 2r from the earth’s centre. Their time periods are in the ratio of
-
- 1 : 2
- 1 : 16
- 1 : 32
- 1 : 2 √2
Correct Option: D
Time period does not depend on the mass.
Also, T2 ∝ r3 .
