The ratio of the nuclear radii of elements with mass numbers 216 and 125 is

A

`6 :5`

B

`sqrt(216):sqrt(125)`

C

`126:125`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Nuclear radius of the mass number `=R_(0)A^(1//3)`
`therefore((R""^(126)X))/((R""^(125)Y))=(3sqrt(216))/(root(3)125)=(6)/(5)`.
