Two particles of mass m each are attached to a light rod of lenght d, one at its centre and the other at a free end. The rod is fixed at the other end and is rotated in a plane at an angular speed w(omega). Calculate the angular momentum of the particle at the end with respect to the particle at the centre. (now see pics. Why is my answer wrong?)
Dear student
We cannot directly subtract the angular momentum of both particles because their relative angular speed is zero.
But they have relative linear speed.
Relative angular momentum = mass x relative speed x relative distance.
momentum depends on speed.
relative momentum depends on relative speed.
