Question: A simple pendulum of length 1 m has a bob of mass 0.3 kg. The energy of this oscillator is quantized to the values En

A simple pendulum of length 1 m has a bob of mass 0.3 kg. The energy of this oscillator is quantized to the values En = (n + 1/2)hf0, where n is an integer and fs is the frequency of the pendulum.

(a) Find n if the angular amplitude is 10o.

(b) Find ∆n if the energy changes by 0.01%.
