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

Options

A. `(r_1)/(r_2)`
B. `((r_1)/(r_2))^2`
C. `(r_2)/(r_1)`
D. `((r_2)/(r_1))^2`

Answer

C

Explanation

rv constant (as Ariel velocity constant.)
`rArr(r_1)/(r_2)=(v_2)/(v_1)`
