The radius of germanium `(Ge)` nuclide is measured to be twice the radius of `._(4)^(9)Be`. The number of nucleons in `Ge` are

Explanation

We use the formula
`R=R_(0)A^(1//3)`
This represents relation between atomic mass and radius of the nucleus.
For berillium `R_(1)=R_(0)(9)^(1//3)`
For germanium `R_(0)=R_(0)A^(1//3)`
`(R_(1))/(R_(2))=((9)^(1//3))/((A)^(1//3))implies2/3((9)^(1/3))/((A)^(1/3))`
`=1/8=9/AimpliesA=8xx9.72`
