Circular velocity isw=v/r
and w=2Pi /T
So, v/r=2Pi /T
Then, r = vT/ 2Pi
T'value is given and if we know velocity we can calculate the distance between the Sun and the Saturn or the radius.
Velocity of the Saturn is approximately 9.6kms-1
Given: T = 29.49yrs
= 29.49.365.24.60.60s
Solution:
r= [{9.6×10^3}×{29.49×365×24×60×60}]÷2Pi
=1.42×10^12m
