A neutron star is a remnant of a massive star that has undergone an explosion called supernova. The neutron star’s mass, which mainly consists of neutrons, can be 1.5 times that of the sun. Yet the neutron star’s radius is only about 6.0 km. Suppose the neutron star is spherical with a radius of 6.0 km, its surface consists of closely packed neutrons, and the pressure beneath the surface layer of neutrons is 1.2 *10^16 Pa. If the surface area of a sphere is 4pier2, what force is exerted by the neutrons?

please help im so confused

anonymous · Answer

Pressure x Surface area gives you total force. (Or more precisely, gives you either the inward force caused by gravity or the outward force of the interior neutrons supporting those on the surface).
