MCQ
Which of the following is wrong statement about binding energy?
  • A
    It is the sum of the rest mass energies of nucleons minus the rest mass energy of the nucleus.
  • B
    It is the energy released when the nucleons combine to form a nucleus.
  • C
    It is the energy required to break a given nucleus into its constituent nucleons.
  • D
    It is the sum of the kinetic energies of all the nucleons in the nucleus.
✓

Answer

  1. It is the sum of the kinetic energies of all the nucleons in the nucleus.

Explanation:

The first three options are correct from the definition of Binding energy.

B.E. has nothing to do with K.E. of the nucleons in nucleus.
