A plenet moving along an elliptical orbit is closest to the sun at a distance `r_(1)` and farthest away at a distance of `r_(2)`. If `v_(1)` and `v_(2)` are the linear velocities at these points respectively, then the ratio `(v_(1))/(v_(2))` is

A

`(r_(2))/(r_(1))`

B

`((r_(2))/(r_(1)))^(2)`

C

`(r_(1))/(r_(2))`

D

`((r_(1))/(r_(2))^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`v_(1)r_(1)=v_(2)r_(2)`
