Question

The energies of macroscopic objects, as well as those of
microscopic objects, are quantized, but the effects of the
quantization are not seen because the difference in energy
between adjacent states is so small. Apply Bohr’s quantization of angular momentum to the revolution of Earth
(mass 6.0 × 1024 kg), which moves with a speed of 3.0 ×
104 m s-1 in a circular orbit (radius 1.5 × 1011 m) about
the sun. The sun can be treated as fixed. Calculate the
value of the quantum number n for the present state of the
Earth–sun system. What would be the effect of an increase
in n by 1?
