In accordance with the Bohr's model, the quantum number that characterises the Earth's revolution around the Sun in an orbit of radius 
with orbital speed 
is [Given: mass of Earth 
]
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Given that, radius of the earth's orbit around the sun, 
Orbital speed of earth, 
Mass of earth, 
According to Bohr's quantization condition of angular momentum, 
Where 
is the Planck's constant and 
is the quantum number
Hence, the quantum number that characterises the Earth's revolution around the sun is 
.
