The satellite of mass m revolving in a circular orbit of radius r around the earth has kinetic energy E. then, its angular momentum will be

A

`sqrt((E)/(mr^2))`

B

`(E)/(2mr^2)`

C

`sqrt(2Emr^2)`

D

`sqrt(2Emr)`

Text Solution

Verified by Experts

The correct Answer is:
C
`E=1/2mv_0^2=1/2((mv_0r)^2)/(mr^2)=1/2(L^2)/(mr^2)`
`L=sqrt(2Emr^2)`
