A neutron star has a density equal to that of the nuclear matter. Assuming the star to be spherical, find the radius of a neutron star whose mass is 4.0 × 10 30 kg (twice the mass of the sun).

Question

Philoid · Accepted Answer

Given mass of star(M) = 4 × 10³⁰ kg

We know,

Density of nuclear matter(D) = 2.3 × 10¹⁷ kg/m³

Again, Volume [As the star is assumed to be a sphere]

[ R = Radius of the neutron star]

So equating the expressions of volume we can say,

⇒

Hence radius of the star is 16.07 km
