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

A

`(d_1^2v_1)/(d_2^2)`

B

`(d_2v_1)/(d_1)`

C

`(d_1v_1)/(d_2)`

D

`(d_2^2v_1)/(d_1^2)`

Text Solution

Verified by Experts

The correct Answer is:
C
From `2^(nd)` law `-v_1d_1=v_2d_2rArrv_2=(v_1d_1)/(d_2)`
