A planet moves around the sun. at a given point `P`, it is closest from the sun at a distance `d_(1)`, and has a speed `V_(1)`. At another point `Q`, when it is farthest from the sun at a distance `d_(2)`, its speed will be

Options

A. `(d_(1)^(2)v_(1))/(d_(2)^(2))`
B. `(d_(2)v_(1))/(d_(1))`
C. `(d_(1)v_(1))/(d_(2))`
D. `(d_(2)^(2)v_(1))/(d_(1)^(2))`

Answer

c

Explanation

`mv_(1)d_(1)=mv_(2)d_(2) rArr v_(2)=(d_(1)v_(1))/(d_(2))`
