Q- Neutron stars are extremely dense objects with a mass comparable to the mass of the sun but a radius of only several thousand meters. Consider a neutron star of mass M = 1.99*1030 kg and a radius of R = 10.2 km.
(a) What is the gravitational acceleration near the surface of the star?
(b) If an incredibly heat-resistant object was dropped near the surface of the star, how fast would it be going after it had fallen a distance of h = 1.5 m?
(c) Assuming uniform density, how much would 1.2 cubic centimeters of neutron star material weigh on the surface of the earth?
