Question

The graph of log$\left( \frac{R}{R_{0}} \right)$ versus log A (R = radius of a nucleus and A = mass number) is-

• A. A circle
• B. An ellipse
• C. A parabola
• D. A straight line

Answer 1

Answer: (D)

A straight line

Answer 2

R = R₀ A^1/3 Ž $\frac{R}{R_{0}}$= A^1/3

log $\left( \frac{R}{R_{0}} \right)$ = $\frac{1}{3}$log A

or y = $\frac{1}{3}x$

a straight line passing through origin with slope 1/3.s
