In accordance with the Bohr’s model, find the quantum number that characterizes the earth’s revolution around the sun in an orbit of radius 3 × 1011 m with orbital speed 3 × 104 m/s. (Mass of earth = 6.0 × 1024 kg.)
r=1.5×1011m; v=3×104m/s;M is the mass of earth. According to Bohr model, Mvr=2πnh. Thus, n=2.6×1074 is the quanta number that charaactrizes the earth revolution.
