Atomic nucleus is central core of every atom in which the whole of positive charge and almost entire mass of atom is concentrated. It is a tiny sphere of a radius R is given by `R=R_(o)A^(1//3)`, where `R_(o)=1.4xx10^(-15)m`, a constant and A the mass number of nucleus
The radius of the nucleus of mass number 125 is

Options

A. `175xx10^(-15)m`
B. `35xx10^(-15)m`
C. `70xx10^(-15)m`
D. `7xx10^(-15)m`

Explanation

`R=R_(0)A^(1//3)`
