A mаgnetаr is а rare type оf rоtating neutrоn star with one of the most powerful magnetic fields in the universe. On March 12, 2020, a magnetar called Swift J1818.0–1607 was discovered in our own Milky Way galaxy, and it is the fastest spinning magnetar ever discovered, spinning at a rate of once every 1.4 seconds! It’s a spherical object with a mass twice that of the Sun (mass of Sun is 1.99 x 1030 kg), but with a diameter less than 20 miles (about 30 km)! Suppose a mysterious force was exerted tangent to the star at it’s equator, causing the rate of spin to slow down to once every 24 hours (like Earth), and suppose it took 1 year (31,557,600 seconds) for this change to take place. a. How much force would be required to cause this change? b. How much torque would be required? c. What would its angular acceleration be? Express this in SI units.
