Two identical satellites A and B are circulating round the earth at the height of R and 2 R respectively, (where R is radius of the earth). The ratio of kinetic energy of A to that of B is

A

`1/2`

B

`2/3`

C

2

D

`3/2`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(A)/K_(B) = r_(B)/r_(A) = (R+h_(g))/(R+h_(A)) = (R+ 2R)/(R+ R) = 3/2`
