Which of the following figure represents the variation of ln R R 0 with ln A (if R = radius of a nucleus and A = its mass number)

Step-by-step solution

We know the relation between radius and atomic mass number is R = R 0 A 1 3 ⇒ ln R = ln R 0 + 1 3 ln A ⇒ ln R R 0 = 1 3 ln A It is similar to y = m x which is equation of line passing through origin.
