Question

A neutron star has a density equal to that of the nuclear matter. Assuming the staar to be spherical, find the radius of a neutron star whose mass is `4.0xx10^30`kg (twice the mass of the sun ).

Answer 1

Correct Answer - `r_(1)=[(4xx10^(30))/(3xx10^(17))xx(1)/(4pi)]^(1//3)= 14.71 km`
(ii) `r_(2)=[(6xx10^(24))/(3xx10^(17))xx(3)/(4pi)]^(1//3)=168.4m`
