Apply Bohr's quantization condition to the motion of the Earth around the Sun.
a) Find a formula for the radii of the allowed circular Earth orbits (involving quantum number n ).
b) What is the difference in radii among the orbit in part (b) and the next larger allowed orbit?
c) The actual radius of the Earth's orbit is about 1.50 x 1011 m. What value of the quantum number n does this correspond to?
