The binding energy per nucleon for the parent nucleus is E1 and that for the daughter nuclei is E2. Then

A nucleus of mass M + Δm is at rest and decays into two daughter nuclei of equal mass M/2 each. Speed of light is c.

(a) E1 = 2E

(b) E2 = 2E1

(c) E1 > E2 

(d) E2 > E1

(d) :- After decay, the daughter nuclei will be more stable, hence binding energy per nucleon of daughter nuclei is more than that of their parent nucleus.
Hence, E2 > E1
