(a) A small ball with a mass of 0.06 kg moves along a circular orbit with a radius of 0.5 m at a speed of 3.0 m/s. What is the angular momentum of the ball?
Angular momentum = mvr
(b) If the angular momentum of this ball were quantized in the same manner as the angular momentum of electrons in the Bohr model of the atom, what would be the approximate value of the quantum number n in such a case?
