Homework Statement
What is the magnitude of the gravitational field at the surface of a neutron star whose mass is 1.80 times the mass of the Sun and whose radius is 9.3 km?
Homework Equations
g = GM/r2
The Attempt at a Solution
G is ofcourse 6.67x10^-11
r^2 is 8.649x10^7 m
Now I don't know what to take as mass. I took just 1.8 and it didn't work. I just took the mass of sun as 1.9x10^30kg and it didn't work and I also tried the product of those two.
What am I missing?
Okay I tried all I could but I am now stuck. Can someone help me. Thanks so much.
