Within a neutron star, the material at the center has a density of 1.0 x 10 18 kg/m 3 . if a small sphere of this material of radius 1.0 x 10 -5 m were some how transported to the surface of the earth, how much would it weigh?

Density of the neutron star is given as

Radius of the star is also given as

now in order to find the mass of star we can assume that star is spherical in shape

so here we can use

now mass of the star will be given as

so weight of the star on the earth will be

so weight on the earth is given by above equation
