Question

Which of the following figure represents the variation of $ln (\frac{R}{R_0})$ with $ln\ A$?
(if $R$ = radius of a nucleus and $A$ = its mass number)

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Answer 2

$R = R_oA^{\frac 13}$

$ln \frac {R}{R_o} = \frac 13 ln\ A$

So, the correct option is (B).
