1.

The angular momentum `(L)` of the earth revolving round the sun uis proportional to `r^(n)`, where `r` is the orbital radius of the earth. The value of `n` is (assume the orbit to be circular)A. 0.5B. 1C. 1.5D. `2.0`

Answer» Correct Answer - a
`v=sqrt((GM)/(R))`
Angular momentum
`L=mRv=mR sqrt((GM)/(R))=msqrt(GM)R^(1//2)`
`therefore" " L prop R^(1//2)`.
