Questions
A satellite of mass m revolving in a circular orbit of radius r around the earth of mass M has a total energy E. Then its angular momentum will be :
detailed solution
Correct option is C
Velocity of the satellite is GMr, angular momentum L =mvrL= mGMr r =mGMr----1given total energy -GMm2r= E⇒GM=2ErmNow, substituting the value of GM in 1L=m2Ermr=2Er2mTalk to our academic expert!
