Two satellites P,Q are revolving around ...

Two satellites `P,Q` are revolving around the earth in different circular orbits. The velocity of `P` is twice the velocity of `Q`. The height of `P` from the earth's surface is `1600 km` . The radius of orbit of `Q` is `(R=6400 km)`

`1600 km`

`20000 km`

`32000 km`

`40000 km`

Text Solution

Verified by Experts

The correct Answer is:

Given , `v_(P)=2v_(Q)`
`sqrt((GM)/(r_(p)))=2sqrt((GM)/(r_(Q)))tor_(Q)=4r_(p)`
