Trajectories of three identical particles in the xy-plane.
Trajectories of three identical particles in the xy-plane.
Three identical particles, each of mass \(m\), move at the same constant speed \(v_0\) in the \(xy\)-plane along three different straight paths:

Particle 1 moves in the \(+x\)-direction along the line \(y = 2d\).
Particle 2 moves along the line \(x + y = 2d\) in the direction of increasing \(x\) and decreasing \(y\).
Particle 3 moves in the \(+y\)-direction along the line \(x = d\).

Which of the following correctly ranks the magnitudes of the angular momenta \(L_1\), \(L_2\), and \(L_3\) of the particles about the origin?
