A neutron star one of highly dense object in our universe which has mass 1.4 x mass of sun. It has too intense gravity (i.e. 2 billion times stronger than earth) is that any object when fall towards the surface look like a tiny particle and speed become comparable of speed of light. Just imagine if Mt. Everest (highest mountain on earth) fall on the surface of neutron star , it is compressed into a small particle due to the intense gravity of neutron star. In following assignment try to understand gravity and its effect on given mass and iron cube
