Rotational motion
(a) Show that [? ̂?,? ̂?] = ?ℏ? ̂?, [? ̂?,? ̂?] = ?ℏ? ̂?, [? ̂?,?
̂?] = ?ℏ? ̂?.
(b) Show that [? ̂2,? ̂?] = 0, and then, without further
calculations, justify the remark that [? ̂2,? ̂?] = 0 for all ? =
?, ?, and ?. What does this mean in terms of uncertainty
principles?

An important special case of the motion of a symmetric top
occurs when it spins about a vertical axis. Analyze this motion as
follows: (a) By inspecting the effective PE,
U_eff(theta)=((L_z-(L_3)cos(theta))^2)/((2lambda_1(sin^2(theta)))+((L_3)^3)/(2lambda_3))+MgRcos(theta),
show that if at any time theta=0, then L_3 and L_z must be equal.
(b) Set L_z=(L_3=lambda_3)(w_3) and then make a Taylor expansion of
U_eff(theta) about theta=0 to terms of order (theta)^2. (c) Show
that if w_3>w_min=2sqrt(MgRlambda_1/((lambda_3)^2), then the
position theta=0 is stable, but if w_3=w_min it is unstable....

3. (10 pts) Heisenberg Uncertainty Principle
The uncertainty principle places a limit on specifying the
location and momentum of a particle simultaneously. Δ?Δ? ≥ ℏ/2 This
is a consequence of the wave nature of particles, which we can see
by examining the uncertainty in the single-slit diffraction of
light.
(a) In single-slit diffraction, the width of the slit ?
represents the uncertainty in x position of the beam, ∆?:
∆? = ?
