If Mo\mathrm{M}_{\mathrm{o}} is the mass of isotope 512B,Mp{ }_5^{12} \mathrm{B}, \mathrm{M}_{\mathrm{p}} and Mn\mathrm{M}_{\mathrm{n}} are the masses of proton and neutron, then nuclear binding energy of isotope is:
View answer and explanation
Correct option: A
(5Mp+7Mn−Mo)C2\left(5 \mathrm{M}_{\mathrm{p}}+7 \mathrm{M}_{\mathrm{n}}-\mathrm{M}_{\mathrm{o}}\right) \text{C}^2
Option A is correct because the nuclear binding energy is the difference between the mass of the individual nucleons and the mass of the nucleus, multiplied by C2\text{C}^2.
