G= 6.67259 × 10-11 Nm2/kg2 After a supernova explosion, a star may undergo a gravitational collapse to an?
extremely dense state known as a neutron star, in which all the electrons and protons are squeezed together to form neutrons. A neutron star having a mass of 1.6 × 1030 kg (about equal tothat of the Sun) would have a radius of about 14.9 km.

C.Find the energy required to remove a particle of mass 7.78 × 10-28 kg from its surface to infinity.
