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_1)/(r_2)`

B

`((r_1)/(r_2))^2`

C

`(r_2)/(r_1)`

D

`((r_2)/(r_1))^2`

Text Solution

Verified by Experts

The correct Answer is:
C
rv constant (as Ariel velocity constant.)
`rArr(r_1)/(r_2)=(v_2)/(v_1)`
