For different satellite revolving around a planet in different circular orbit, which of the following shows the relation between the angular momentum L and the orbital radius r?

A

`L prop r^2`

B

`L prop sqrtr`

C

`L prop 1/r^2`

D

`L prop 1/sqrtr`

Text Solution

Verified by Experts

The correct Answer is:
B
`implies (mv^2)/r = (GMm)/r^2`
Now angular momentum L = mvr
`= msqrt((GM)/r )xx r =m sqrt(GMr)`
