A pulsar is a rapidly rotating neutron star The Crab Pulsar

A pulsar is a rapidly rotating neutron star. The Crab Pulsar is located in the Crab Nebula in the constellation Taurus. The pulsar is in the center of the close-up view of the nebula shown in the photograph. The periods of pulsars can be measured with great accuracy: The Crab Pulsar has a period of 0.033 s. (a) Find the pulsar\'s angular velocity. (b) The radius of the pulsar is estimated to be 10 km. Find the tangential velocity of a point on its equator.

Solution

T = 0.033 s = 2/w => w=190.4 rad/s Ans(a)

r = 10 km = 10000 m

tangential velocity at equator,v = rw = 1903995.55 m/s = 1.904*10⁶ m/s Ans(b)
