The graph of `1n (R/R_0)` versus `1n A (R = radius` of a nucleus and `A =` its mass number) is

The ratio of r_(n)//r_(0) (r_(n) = "radius of nucleus and "r_(0)"is radius of atom ")

A : Nuclear density is almost same for all nuclei . R: The radius (r ) of a nucleus depends only on the mass number (A) as r prop A^(1//3) .

A : Nuclear density is almost same for all nuclei . R: The radius (r ) of a nucleus depends only on the mass number (A) as r prop A^(1//3) .

If A is mass number of a nucleus of Radius R, then

Size of nucleus was obtained by the equation r=R_(0)A^(1//3) , Where r is the radius of nucleus of mass no A. and R_(0) is a constant whose valie is equal to 1.5xx10^(-15) metre. (Given : 1 amu = 1.66xx10^(-24)g ) What is the density of a nucleus of mass number A ?
