In an experiment where we will use a vertically-mounted turntable that has a hub attached at its center, which has three grooves of different radius, around which one can wind a string. A mass hanging from the free end of the string provides tension, which exerts a torque on the turntable, thus causing it to rotate What effect does the diameter of the string have on the lever arm? Explain why we can ignore this effect. Please help guide me as to what the string's diameter's effect is on the lever arm, and why this effect can be ignored.

The ammonia molecule can be treated as a symmetric rigid rotator, with its 3 hydrogen atoms lying in the xy plane and the nitrogen atom lying above the plane on the z axis, as shown in the attached image. If we call the moment of inertia about the z acis I3, and the moments about the pair of axes perpendicular to the z axis I1, the rotational energy of the molecule can be written as Eq 1 (see provided image). Say that at time t = 0, the wave function of the ammonia molecule is given as Eq 2 (see provided image), where the Yl, m1(θ, Φ) are the sphereical harmonics. Determine the probability that a measure of the rotational energy of the molecule yields the value 0 for the state ψ. What is <E> for this state?
