 For satellite rotating in an orbit around the earth the ratio of kinetic energy to potential energy is ...........

A

`1/2`

B

`1/sqrt2`

C

2

D

`sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
A
`implies U = - (Gmem)/(R_e)`
`K=1/2 mv_0^2`
`=1/2m(sqrt((GM_e)/R_e))^2`
`=1/2 (GM_em)/R_e`
`=U/2` taking only value
`:. K/U = 1/2`
