Black holes have all their mass packed into a single point (known as singularity). how does this affect the gravitational force on an object close to the black hole? newton’s formula for the force of gravity between two masses (m1 and m2), where r is the distance between the centers of the two objects, is f=gm1m2r2f=gm1m2r2. 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.
