Suppose we're in two dimensions, and both particles have mass 1.(adsbygoogle = window.adsbygoogle || []).push({});

Particle 1's location is given by its polar coordinates [itex](r_1,\theta_1)[/itex]; likewise for Particle 2 [itex](r_2,\theta_2)[/itex].

Is it true that the total angular momentum [itex]\vec{L}[/itex] is just the sum of the individual angular momenta of the particles: [itex]\vec{L} = \vec{L}_1 + \vec{L}_2[/itex]? If that's the case, can you give me the total angular momentum operator [itex]\vec{L}[/itex] as a differential operator?
