A planet is revolving in an elliptical orbit around the Sun. Its closest distance from the Sun is r_min and the farthest distance is r_max. If the velocity of the planet at the distance of the closest approach is v₁ and that at the farthest distance from the Sun is v₂, then v₁/v₂ 

• A

  $\frac{{\mathrm{r}}_{max}}{{\mathrm{r}}_{min}}$

• B

  $\frac{{\mathrm{r}}_{min}}{{\mathrm{r}}_{max}}$

• C

  $\frac{{\mathrm{r}}_{min}+{\mathrm{r}}_{max}}{{\mathrm{r}}_{max}-{\mathrm{r}}_{min}}$

• D
