In a massive star supernova explosion, a stellar core collapses to form a neutron star roughly 10 kilometers in radius. The gravitational potential energy released in such a collapse is approximately equal to GM2/r where M is the mass of the neutron star, r is its radius, and G=6.67×10−11m3/kg×s2 is the gravitational constant.
PART A: Using this formula, estimate the amount of gravitational potential energy released in a massive star supernova explosion.
