The time period of revolution of a satel...

The time period of revolution of a satellite is T. The kinetic energy of the satellite is proportional to:

A

`T^(-2//3)`

B

`T^(3)`

C

`T^(2)`

D

`T`

Text Solution

Verified by Experts

The correct Answer is:
A
`K.E. =(GMm)/(2r) rArr E_(k) prop (1)/(r )`
Also `T^(2)prop r^(3) rArr r prop T^(2//3)`.
`therefore E_(k) prop T^(-2//3)`
So the correct choice is (a).
