`r_(1)` and `r_(2)` are the radii of atomic nuclei of mass numbers `64` and `27` repsectively. The ratio `(r_(1)//r_(2))` is

A

`64//27`

B

`27//64`

C

`4//3`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
C
`As (r _(1))/(r _(2))= ((A_(1))/( A _(2))) ^(1//3) = 1.2 xx 10 ^(-13) =((64)/(27))^(1//3) = 4/3`
