(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A neutron star has a radius of 10,000 km, and takes a planet 30 days to complete one revolution around the star. When the star collapses, the new radius is 3 km. Find the new period of revolution of the newly formed neutron star.

2. Relevant equations

T=2(pi)/omega

omega = (v cross r)/r^2

3. The attempt at a solution

Not sure even how to approach this. i'm so confused and i can't find the velocity to find omega!! this is my first post on PF, any help please?!
