quantum mechanics - Coupled Harmonic Oscillator - Solve by diagonalization




I have a problem where I have two massive Particles M and one particle with mass $m

This probably means to switch to new coordinates y1=q1+q2y2=12q112q2+q3y3=12q1+12q2+q3


But what do I do with the momentum operators. They should change accordingly but I am confused as to how exactly

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
