D
Decrease in the binding energy is proportional to surface area. (E) While estimating the surface energy, it is assumed that each nucleon interacts with 12 nucleons, 
and 
are constants) Choose the most appropriate answer from the options given below:
B, C only
and are constants) Choose the most appropriate answer from the options given below: B, C only
Text Solution
Verified by ExpertsThe correct answer is:
A
Surface energy per nucleon 
(Mass number 
).
is incorrect
Contribution to binding energy by columbic forces is
is incorrect
Volume energy 
is correct
For , if we consider only surface energy contribution then option is correct.
For (E) only 3 interactions contribute to surface energy.
