  • Question 1
    4 / -1

    A nucleus of mass M + ∆m is at rest and decays into two daughter nuclei of equal mass (M/2) each. Speed of light is c.
    The binding energy per nucleon for the parent nucleus is E1 and that for the daughter nuclei is E2. Then,

  • Question 7
    4 / -1

    A radioactive element X converts into another stable element Y. Half life of x is 2 hrs. Initially, only X is present. After time t, the ratio of atoms of X and Y is found to be 1 : 4. Then t in hours is

    Electrons in the atom are held to the nucleus by

  • Question 9
    4 / -1

    In Rutherford experiment, a 5.3 MeV a – particle moves towards the gold nucleus (Z = 79). How close does the alpha particle to get the centre of the nucleus, before it comes momentarily to rest and reverses its motion?
