A planet is revolving in an elliptical orbit around the sun. Its closest distance from the sun is r and the farthest distance is R. If the velocity of the planet nearest to the sun be v and that farthest away from the sun be V. then v/V is

Options

A. `x//y`
B. `y//x`
C. `x^(2)//y^(2)`
D. `y^(3)//x^(2)`

Answer

a

Explanation

`v_("max")r_("min")=v_("min")r_("max")`
`ux=vy`
`therefore" "(v)/(u)=(x)/(y)`
