##-\frac{KM^2}{r^2}+Mr\dot{θ}^2 = M\ddot{r} ##? The particle , with origin at the center of the sphere . 'r' is the distance from the origin(center of sphere) to the particle . Is it wrong ?

Thanks . Do you think reducing to a one body problem is the best way to solve this problem ? Or is there an alternative approach ?

What is the mass at the fixed center of attraction ? Is it equal to the sum of the two bodies involved ?

I was not thinking in terms of reduced mass . I was considering the problem as two body problem only . What is the mistake ?

In polar coordinates ,taking origin to be at the center of moving sphere ,the force equation is ##-\frac{KM^2}{r^2}+r\dot{θ}^2 = \ddot{r}## . Am I right ? I am fairly new with polar coordinates . What should be the next step ? Should I conserve angular momentum with respect to the Center of Mass ?

Thanks

Is the sphere also moving in the problem?

Is the sphere fixed (or is it also moving under the influence of the particle)?
