Question
Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but a much smaller diameter.. If you weigh 670 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 25.0 km ? Take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be G = 6.67×1011 Nm2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 . Express your weight wstar in newtons.
Explanation / Answer
w=?
m=670 N
g=?
Solution:
radiusof neutron star 11.5 km=11,500meters
we need to find to find g on the neutron star: so
g=GM/r*2
puting values
g= 6.67*10e-10*1.99*10e30/11,500e2
g=1*10e12
w= 670*1*10e12
w=6.7*10e14 N ans
