Nucleus: Composition, Size & Nuclear Force

The mass number of nucleus having radius equal to half of the radius of nucleus with mass number 192 is:

Show answer and solution

Answer: (b)

  1. A∝R3A \propto R^3, so halving RR divides AA by 23=82^3 = 8.
  2. A=1928=24A = \frac{192}{8} = 24
  3. So the answer is (b) 24.
