The distances of two satellites P and Q ...

The distances of two satellites P and Q from earth are in the ratio `3:1`. The ratio of their total energy will be:

A

`1:1`

B

`(1)/(3):1 `

C

`3:1`

D

`1:3`

Text Solution

Verified by Experts

The correct Answer is:
D
Total energy `E=-(GMm)/(2r) therefore (E_(1))/(E_(2))=(r_(2))/(r_(1))=(1)/(3)`
So correct choice is (d).
