Type: MCQ-numerical-Medium
The radius of a spherical nucleus as measured by electron scattering is 3.6 fm. What is the mass number of the nucleus most likely to be?
A
27
B
40
C
56
D
120
Correct Answer
Option A
Detailed Explanation
Nuclear radius, R = R₀(A)¹/³ where A is the mass number of a nucleus. Given, R = 3.6 fm. 3.6 fm = (1.2 fm)(A)¹/³ [∵ R₀ = 1.2 fm] or A = (3)³ = 27.
