I'm doing the experiment for a project using a setup as so:

In the derivation of the formula I used the amplitude of the oscillation on the ruler of the laser, basically taking it as the arclength of the arc drawn by the laser spot as the bar rotates inside the apparatus and got the same formula as given to me by an instructor:

He has written the value I used as the arclength of the laser as the "difference of scale readings of the equilibrium positions of the spot corresponding to the two arrangements (A) and (B) "
Positions A and B being the two possible positions of the large spheres.
Can anyone explain what this means? Why is there a difference between the equilibrium positions and how does that equal the arclength the laser draws out?
