Problem
A neutron star has a radius of 50.0 km and completes one revolution every 25 ms.
(1) Calculate the centripetal acceleration experienced at the equator of the star.
(2) The acceleration of free fall at the surface of the star is 8.0×1010 m s−2 . State and explain whether a probe that landed on the star can stay on the surface or whether it will be thrown off.
