The Crab Pulsar is a neutron star, rotating with a period of 33.085 ms. It is estimated to have an equatorial radius of 15 km, about average for a neutron star. What is the radial acceleration of an object on the surface at the equator of the pulsar? A) 5.4 x 10⁸ m/s² B) 2.7 x 10⁸ m/s² C) 8.9 x 10⁸ m/s² D) 6.7 x 10⁸ m/s²

Question

The radial acceleration can be calculated using the formula a = ω²r, where ω = 2π/T. For the Crab Pulsar, T = 33.085 ms = 0.033085 s, and r = 15,000 m. Calculating ω and then a gives approximately 5.4 x 10^8 m/s².
