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

A

its speed is maximum

B

time period of its rotation is minimum

C

the total energy of the earth plus satellite system is minimum

D

the total energy of the earth plus satellite system is maximum

Text Solution

Verified by Experts

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