The satellite of massmrevolving in a circular orbit of radiusraround the earth has kinetic energyE. Then its angular momentum will be

Options:

Answer:
C
Solution:

Ifmis the mass andvis the orbital velocity of the satellite, then kinetic energy.

                   E=12mv2

or           Em=12m2v2

or       m2v2=2Em

or            mv=2Em                           ….i

 Ifris the radius of the orbit of the satellite, then its angular momentum

                   L=mvr

Using Eq. (i),

         L=2Emr=2Emr2
