The desity of a nucleus in which mass of each nucleon is `1.67xx10^(-27)kg` and `R_(0)=1.4xx10^(-15)m` is

Options

A. `1.453xx10^(17)kg//m^(3)`
B. `1.453xx10^(16)kg//m^(3)`
C. `1.453xx10^(21)kg//m^(3)`
D. `1.453xx10^(10)kg//m^(3)`

Answer

A

Explanation

`d=(Am)/((4)/(3)pi R^(3))=(3Am)/(4pi(R_(0)(1)/(A^(3)))^(3))=(3Am)/(4 pi R_(0)^(3)A)=(3m)/(4 pi R_(0)^(3))`
