Mass of certain spherical neutron star is twice size of sun

Reference no: EM13655344

Suppose a mass of a certain spherical neutron star is twice the size of the sun and its radius is 10km. Determine the greatest possible angular speed the star can have so that the matter at its surface on the equator is just held in orbit by the gravitational force.
