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

A

2

B

`sqrt2`

C

`1/2`

D

`(1)/(sqrt2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`(GMm)/(R^2) = m omega^2 R`
`KE = 1/2 I omega^2 = 1/2 mR^2 omega^2 = (GMm)/(2R)`
`PE = - (GMm)/(R )`
`(KE)/(|P.E|) = (GMm)/(2R) xx (R )/(GMm) = 1/2 `
