The time period of a satellite is T when it is orbiting around the earth in a circular orbit of radius r. If the same satellite is orbiting around a planet that has a mass double of the earth and the radius of the circular orbit on that planet is also r, then the time period of the satellite for this planet will be:
1
\(\frac{T}{2}\)
2
\(\frac{T}{\sqrt2}\)
3
2T
4
None of these
