Question
A nucleus of mass M + Δm is at rest and decays into two daughter nuclei of equal mass M/2 each. The speed of light is c.
The binding energy per nucleon for the parent nucleus is E1 and that for the daughter nuclei is E2. Then
-
E1 = 2E2
-
E2 = 2E1
-
E1 > E2
-
E2 > E1
Solution
D.
E2 > E1
After decay, the daughter nuclei will be more stable hence, binding energy per nucleon will be more than that of their parent nucleus.
