The Crab Pulsar Is a Neutron Star, Rotating with a Period

Multiple Choice

The Crab Pulsar is a neutron star, rotating with a period of about 33.085 ms. It is estimated to have an equatorial radius of 15 km, about average for a neutron star. The pulsar is slowing in its rotation so that it is expected to come to rest 9.5 × 10¹⁰ s in the future. Assuming it is slowing with a constant angular acceleration, what is the tangential acceleration of an object on the neutron star's equator?

A) 3.0 × 10⁻⁵ m/s²
B) 2.0 × 10⁻⁹ m/s²
C) 3.2 × 10⁻¹⁰ m/s²
D) 7.6 × 10⁻⁷ m/s²
E) 4.8 × 10⁻⁶ m/s²
