A planet moving along an elliptical orbit is closest to the Sun at distance `r_(1)` and farthest away at a distance of `r_(2)`. If `v_(1)` and `v_(2)` are linear speeds 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`
