    4 / -1

  • Question 3
    4 / -1

    Calculate the energy released when three α-particles combined to form a 12C C nucleus, the mass defect is (atomic mass of 2He4 is 4.002603 u)

  • Question 4
    4 / -1

    If M is the atomic mass and A is the mass number, packing fraction is given by

  • Question 5

  • Question 7
    4 / -1

    Mass of the nucleons together in a heavy nucleus is

  • Question 8
    4 / -1

    If a star can convert all the He nuclei completely into oxygen nuclei, the energy released per oxygen nuclei is (mass of the nucleus is 4.0026 amu and mass of oxygen nucleus is 15.9994 amu)

  • Question 9

  • Question 10
    4 / -1

    Two nucleons are at a separation of one Fermi. Protons have a charge of + 1.6 × 10-19 C. The net nuclear force between them is F1, if both are neutrons, F2 if both are protons and F3 if one is proton and other is neutron
