The angular momentum of the earth revolving round the sun is proportional to

r^n

, where

r

is the distance between the centres of earth and the sun. The value of

n

is

View answer and explanation

Correct option: D

\frac{1}{2}

The correct answer is D (

\frac{1}{2}

) because the angular momentum is proportional to

r^{\frac{1}{2}}

, derived from Kepler's laws and the definition of angular momentum.
