The potential energy os a body of mass 100 kg is circulating in orbit at a height of 600 km above the surface of earth is
(Radius of earth 6400 km, mass of earth `=6xx10^(24)" kg and G"=2//3xx10^(-10)Nm^(2)//kg^(2))`

A

`-5.16xx10^(9)J`

B

`-5.50xx10^(9)J`

C

`-5.70xx10^(9)J`

D

`-2.95xx10^(9)J`

Text Solution

Verified by Experts

The correct Answer is:
c
`"P.E. "=-("GMm")/((R+h))=-(2xx10^(-10)xx6xx10^(24)xx100)/(3xx7xx10^(6))`
`=-0.57xx10^(10)=-57xx10^(9)J`
