The Crab Pulsar, location inside the Crab Nebula in the constellation Orion, has a period currently of length 33.085 ms. Itis estimated to have an equatorial radius of 15 km. a). What is the value of centripetal acceleration of a an object on the surface atthe equator of the pulsar? b) Many pulsars are observed to have periods that lengthen slightly with time, a phenomenon called "spindown." The rate of slowing the crab pulasr is 2.5*10-13 which implies that if the rate of remainsconstant the pulasr will stop spinning in 9.5 *1010 seconds. What is the tangential acceleration of the object on the equator of this neutron star?
