A nucleus disintegrates into two nuclear fragments which move apart, having their velocities in the ratio 1:3. The ratio of their nuclear sizes, respectively, will be

Answer the question on basis of passage given below :
The noble gases have closed shell electronic configuration and are monatomic gases under normal conditions. The low boiling points of lighter noble gases are due to the weak dispersion forces between the atoms and the absence of other inter atomic interaction. The direct reaction of xenon with fluorine leads to
