A satellite of mass m is circulating around the earth with constant angular velocity. If radius of the orbit is r and mass of the earth M, the angular momentum about the centre of the earth is :

Answer»

`m sqrt((GM)/(R ))`
`M sqrt(Gmr)`
`M sqrt((GM)/(r ))`
`m sqrt(GM r)`

Solution :`L=mv" "FC=m sqrt((GM)/(r )).R=m sqrt(GMr)`
So the correct CHOICE is (d).
