A main-sequence star of 3 solar masses has a radius of approximately 2.5 times the radius of our Sun. According to Newton’s formula, what would happen to the gravitational force felt by an object on the surface of this 3-solar-mass star if the star’s entire mass gradually collapsed to a singularity? Assume the object remains on the surface of the star throughout the collapse.
