Question
(a) A star with the mass (M = 2.0 x 10^30 kg) and size (R= 3.5 x 10^8 m) of the sun rotates once every 32.0 days. After gravitational collapse, the star forms a pulsar that is observed by astronomers to emit radio pulses every 0.200s. By treating neutron star as a solid sphere, deduce its radius.
Express your answer with the appropriate units.
(b) What is the speed of a point on the equator of the neutron star? Your answer will be somewhat too large because a star cannot be accurately modelled as a solid sphere.
Express your answer with the appropriate units.
