Nuclei

Question
CBSEENPH12047765
Wired Faculty App

If Mo is the mass of an oxygen isotope 8O17 , MP and Mn are the masses of a proton and a neutron, respectively, the nuclear binding energy of the isotope is

  • ( Mo - 8 MP ) c2 

  • ( Mo - 8 MP - 9 Mc ) c2

  • Mo C2

  • (Mo - 17 Mn ) c2

Solution

B.

( Mo - 8 MP - 9 Mc ) c2

Binding energy:- If a certain number of protons and neurons are brought together to form a nucleus to form a nucleus of a certain charge and mass, an energy Eb will be released in the process. The energy Eb is called the binding energy of the nucleus.

BE = ( Mnucleus - Mnucleons ) c2

BE = (Mo - 8MP - 9 Mn ) c2
