A nucleus disintegrates into two nuclear parts which have their velocities in the ratio

\mathrm{2:1}

. The ratio of their nuclear sizes will be

View answer and explanation

Correct option: D

1:{2^{1/3}}

Option D (

1:{2^{1/3}}

) is correct because the ratio of nuclear sizes is inversely proportional to the ratio of their velocities, and the radius is proportional to the cube root of the mass number.
