If a satellite orbits as close to the earth's surface as possible,

A

its speed is maximum

B

toime period of its rotation is minimum

C

the total energy of the' earth satellite' system is minimum

D

the total energy of the' earth satellite' system is maximum

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`v=sqrt((GM)/(r )), T=2P sqrt((r^(3))/(GM)), TE = -(GMm)/(2r)`
For satellite orbitting close to earth `r = r_(min)=R`
so option (A), (B), (C ) are correct choice.
