The nuclear radius of a nucleus with nucleon number 16 is $3{\rm{ }} \times {\rm{ }}10{\;^{ - 15}}$ metre. Then the nuclear radius of a nucleus with nucleon number 128 is

$6{\rm{ }} \times {\rm{ }}10{\;^{ - 15}}m$

$3{\rm{ }} \times {\rm{ }}10{\;^{ - 15}}m$

$1.5{\rm{ }} \times {\rm{ }}10{\;^{ - 15}}m$

$4.5 \times {\rm{ }}10{\;^{ - 15}}m$

The nuclear radius of a nucleus with nucleon number 16 is

3\mathrm{ } \times \mathrm{ }10{\;^{ - 15}}

metre. Then the nuclear radius of a nucleus with nucleon number 128 is

View answer and explanation

Correct option: C

6\mathrm{ } \times \mathrm{ }10{\;^{ - 15}}m

Option C (

6\mathrm{ } \times \mathrm{ }10{\;^{ - 15}}m

) is correct because the nuclear radius is proportional to the cube root of the nucleon number.
