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?
