Question

A communication satellite of earth which takes
24 hrs, to complete one circular orbit eventually
has to be replaced by another satellite of double
mass. If the new satellites along has an orbital
time period of 24 hrs, then what is the ratio of
the radius of the new orbit to the original orbit ?
[BHU-2004)
(1) 1:1 (2) 2:1 (3) v2 : 1(4)1:2​

Answer 1

Answer:

⟹ for same time period, radius of the orbit will be same.

Hence r':r=1:1
