Solution

Step 1: Given that:

The binding energy per nucleon for O16 = 7.97MeV

The binding energy per nucleon for O17 = 7.75MeV

Step 2: Calculation of energy (in MeV) required to remove a neutron from O17 :

We have;

O17O16+10n

Thus,

Energy required= Binding energy per nucleon of O17 Binding energy per nucleon of O16 = 17×7.7516×7.97

= 131.75 127.52

= 4.23MeV

Thus,

The energy required energy (in MeV) required to remove a neutron from O17 is 4.23MeVThus,

Option D) 4.23MeV is the correct option.
