Question

One of the possible final outcomes of a stars life cycle is the formation of a neutron which are extremely massive but relatively small objects. A typical neutron start is only 20 kilometers in diameter but has a mass approximately 1.4 times that of our sun msun=2x1030kgm_{sun}=2x10^{30}kgmsun =2x1030kg. What is the acceleration due to gravity on the surface of a neutron start

275,383 m/s2

9.8 m/s29.8\ m/s^29.8 m/s2

275 m/s2275\ m/s^2275 m/s2

1.9x1012 m/s21.9x10^{12}\ m/s^21.9x1012 m/s2

4.7x1011 m/s24.7x10^{11}\ m/s^24.7x1011 m/s2
