Question

How does the binding energy per nucleon vary as the mass number of nuclei increases?

G1 Physics · Accepted Answer

For light nuclei, binding energy per nucleon rises rapidly as A increases. It reaches a maximum around Fe/Ni (A ≈ 56–62), then slowly decreases for heavier nuclei due to increasing Coulomb repulsion. Final answer: Option C.
