The graph of versus is where is radius of a nucleus, is its mass number, and is constant
- A A straight line
- B A circle of radius \(R\)
- C A parabola
- D An ellipse
Answer & Solution
Correct Answer
(A) A straight line
Step-by-step Solution
Detailed explanation
Using the relation mass number A and radius R of a nucleus, R=R0A13 ...(1) Taking the logarithm of both sides, lnR=lnR0A13=lnR0+13lnA⇒lnRR0=13lnA Hence, the graph of lnRR0 vs. 13lnA will be a straight line.
