The ratio between the radii of nuclei with mass numbers 27 and 125 is

A

`5:3`

B

`3:5`

C

`27:125`

D

`125:27`

Text Solution

Verified by Experts

The correct Answer is:
B
Radius of nuclei `R=R_(0)A^(1//3)`
`therefore (R_(1))/(R_(2))=((A_(1))/(A_(2)))^(2//3)`
or `(R_(1))/(R_(2))=((27)/(125))^(1//3)=(3)/(5)`
