The maximum and minimum distance of a comet form the sun are `8xx10^(12)m and 1.6xx10^(12)m`. If its velocity when nearest to the sun is `60m//s`, what will be its velocity in m/s when it is farthest

A

12

B

60

C

112

D

6

Text Solution

Verified by Experts

The correct Answer is:
A
vr=Constant
`rArr(v_1)/(v_2)=(r_2)/(r_1)rArr60/(v_2)=(8xx10^(12))/(1.6xx10^(12))rArrv_2=12m//s`
