The volume of a nucleus is directly proportional to

Options

A. A
B. `A^(3)`
C. `sqrtA`
D. `A^(1//3)`

Answer

A

Explanation

Radius of nucleus R = `R_(0) A^(1//3)` where A is the mass number of nucleus
`therefore` Volume of nucleus = `(4)/(3) pi R^(3) = ((4)/(3) pi R_(0)^(3)) A`
`therefore` Volume is proportional to A .
