Suppose that the gravitational attractio...

Suppose that the gravitational attraction between a star of mass M and a planet of mass m is given by the expression `F=K(Mm)/(r^(2))` where K and n are constants. If the orbital peed of the planets were found to be independent of their distance (r) from the star, calculate the time period `(T_(0))` of a planet going around the star in a circular orbit of radius `r_(0).`

Text Solution

Verified by Experts

The correct Answer is:
`T_(0)=(2pir_(0))/(sqrt(KM))`
