A planet moving along an elliptical orbit is closest to the sun at a distance r1 and farthest away at a distanced of r2. If v1 and v2 are the linear velocities at these points respectively. Then the ratio v1/v2 is

Q: A planet moving along an elliptical orbit is closest to the sun at a distance r1 and farthest away at a distanced of r2. If v1 and v2 are the linear velocities at these points respectively. Then the ratio v1/v2 is

(b) $(\frac{r_1}{r_2})^2$

(c) $\frac{r_2}{r_1}$

(d) $(\frac{r_2}{r_1})^2$
