Two nuclei may have the same radius, even though they contain different numbers of protons and neutrons. Explain.

उत्तर
Radius of nucleus depends on the total number of neutrons and protons.
Let assume one nucleus has n1 neutrons and p1 protons. The second nucleus has n2 neutrons and p2 protons. If
n1 + p1 = n2 + p2
then the radius of the two nuclei will be equal even though they are having a different number of neutrons and different numbers of protons.
