COMEDK · Physics · 29. Nuclear Physics
The ratio of the radii of the nucleus of two element \(\mathrm{X}\) and \(\mathrm{Y}\) having the mass numbers 232 and 29 is:
- A 1 : 4
- B 1 : 2
- C 4 : 1
- D 2 : 1
Answer & Solution
Correct Answer
(D) 2 : 1
Step-by-step Solution
Detailed explanation
The radius of a nucleus is given by the formula \(R = R_{0} A^{1/3}\), where \(R_{0}\) is a constant and \(A\) is the mass number of the nucleus. For the two elements X and Y, the ratio of their radii is given by…
