Which of the following two physical quantities cannot be measured simultaneously with arbitrary accuracy for the motion of a quantum particle in three dimensions? (a) square of the radial position and z. -component of angular momentum (r² and L.) (b) x-components of linear and angular momenta (p, and L) (c) y -component of position and z. -component of angular momentum (y and L) (d) squares of the magnitudes of the linear and angular momenta (p² and Ľ²) Which of the following two physical quantities cannot be measured simultaneously with arbitrary accuracy for the motion of a quantum particle in three dimensions?
