QAIPMT-2002-Ch-2759: NEET 2003 Physics - Class 12 AIPMT-2002-Ch-2759 Solution: The mass of proton is 1.0073 u and that of neutron is 1.0087 u…
The mass of proton is 1.0073 u and that of neutron is 1.0087 u (u = atomic mass unit). The binding energy of is (Given helium nucleus mass 4.0015 u.)
Multiple Choice Options
- A 0.0305 J
- B 0.0305 erg
- C 28.4 MeV
- D 0.061 u
Step-by-Step Verified Solution
Mass defect( _ m) = 2M P
+ 2M N � M He
_ _ m = 2 _ 1.0074 + 2 _ 1.0087 � 4.0015
_ _ m = 0.0307
Now as per relation, E = _ m _ 931 MeV
= 0.0307 _ 931 = 28.4 MeV
