So a light particle is orbiting a massive particle by gravity.
We take both particles as spot particles.
The light particle makes an eccentric orbit where maximum radius of the orbit equals 2 and minimum radius equals 1.
I suppose the mass of the massive particle such that the speed of the light particle at the farthest radius is 1 m/s
According Newton when you double the radius of an orbit its speed decreases by a factor of square root of two
So when the orbit is at a distance of 1 m its speed will be equal to square root of 2=1.41 m/s
So how is angular momentum conserved here for initial angular momentum is mvr=2 and final angular momentum=1.41?
