Consider the following two statements A and B and identify the correct answer given below.
A. Nuclear density is same for all nuclei.
B.Radius of the nucleus R and its mass number A are related as `sqrt(A) alpha R^(1/(6))`.

Options

A. Both A and B are true
B. Both A and B are false
C. A is true but B is false
D. A is false but B is true

Answer

C

Explanation

A. Density remains constant for all nuclei which is equal to `10^(17) kgm^(-3)`
B. `R=R_(0)A^(1/3)`
`R alpha A^(1/3)`
`R^(3)alpha A`
`sqrt(A)alpha R^(3/2)`
Thus A is true and B is false.
