Options

• 2

• 1

• 1/2

• 3/2

Answer 1

Angular momentum of the earth revolving around the sun is proportional to rⁿ , where r is the distance between the earth and the sun. Value of n is 2.

Explanation:

`L prop  r^n` 

` therefore omegamr^2 prop r^n    ..... because L = Iomega`

`therefore n = 2             ...... [momega` = constant]
