For a satellite moving in an orbit around the earth, the ratio of kinetic energy of potential

A

`1/2`

B

`(1)/(sqrt2)`

C

`2`

D

`sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
A
`(GMm)/(R^2) = m omega^2 R`
` K.E = 1/2 omega^2 = 1/2 mR^2 omega^2 = (GMm)/(2R)`
` P.E = - (GMm)/(R )`
So, `(KE)/(|PE|) = 1/2 `
