Physics - Gravitation Question with Solution | TestHub

In a certain universe the gravity is a conservative force, but not necessarily an inverse square law force. In that universe, there exists a point like mass m that is influenced only by gravity. As a result of gravitational force the mass orbits the fixed source (point O ) in a circle, so that the source point is on circle's rim. If force as a function of r is $\frac{4{\mathrm{xmR}}^4{\mathrm{v}}_0^2}{{\mathrm{r}}^5}$. Calculate x . (where r is distance from m to o )
