1.	Find the angular momentum of a satellite of mass m moving round the earth of mass m if its orbital radius is r, assuming it to be circular. Express it in terms of G, M, m and r, where G is the universal gravitational constant ?
Answer» Solution :`L = mvr, GMm//R^(2) =mv^(2)//r, V =(GM//r)^(1//2), L =m xx (GMllr)^(1//2) xx r =(GMm^(2)r)^(1//2)`
