If the distance between nuclei is $2\,\, \times \,{10^{ - 13}}\,{\rm{cm}}$, the density of nuclear material is

$4\,\, \times \,\,{10^{17}}\,\,{\rm{kg}}{{\rm{m}}^{ - 3}}$

$3.21\,\, \times \,\,{10^{ - 12}}\,\,{\rm{kg}}{{\rm{m}}^{ - 3}}$

$1.6\,\, \times \,\,{10^{ - 3}}\,\,{\rm{kg}}{{\rm{m}}^{ - 3}}$

$2\,\, \times \,\,{10^9}\,\,{\rm{kg}}{{\rm{m}}^{ - 3}}$

If the distance between nuclei is

2\,\, \times \,{10^{ - 13}}\,\mathrm{cm}

, the density of nuclear material is

View answer and explanation

Correct option: D

4\,\, \times \,\,{10^{17}}\,\,\mathrm{kg}{\mathrm{m}^{ - 3}}

Option D (

4 \times 10^{17} kg/m^3

) is correct because nuclear density is approximately constant and independent of the mass number, and it can be calculated using the mass of a nucleon and the volume of the nucleus.
