  • Question 1
    4 / -1

    The wavelengths of Kα x-rays of two metals ‘A’ and ‘B’ are  respectively, where ‘R’ is Rydberg constant. The number of elements lying between ‘A’ and ‘B’ according to their atomic numbers is

    Solution

  • Question 2
    4 / -1

    A free neutron decays to a proton but a free proton does not decay to a neutron out side nucleus. This is beacuse

    Solution

    As proton mass is less than neutron mass proton does not decay to neutron outside nucleus.

  • Question 3
    4 / -1

    An α a particle with a kinetic energy of 2.1 eV makes a head on collision with a hydrogen atom moving towards it with a kinetic energy of 8.4 eV. The collision.

    Solution

    For completely inelastic collision both come to rest after collision and net energy of

    4E + E = 10.5 eV is lost. But electron in ground state of H-atom can accept only an energy of 10.2 eV.

    Hence the collision may be inelastic but it can never be perfectly inelastic.

  • Question 4
    4 / -1

    A monochromatic radiation of wavelength λ is incident on a sample containing He+. As a result the Helium sample starts radiating. A part of this radiation is allowed to pass through a sample of atomic hydrogen gas in ground state. It is noticed that the hydrogen sample has started emitting electrons whose maximum Kinetic Energy is 37.4 eV. (hc = 12400 eV Å) Then λ is -

    Solution

  • Question 5
    4 / -1

    The work function of a certain metal is  When a monochromatic light of wavelength λ < λ0 is incident such that the plate gains a total power P. If the efficiency of photoelectric emission is η% and all the emitted photoelectrons are captured by a hollow conducting sphere of radius R already charged to potential V, then neglecting any interaction between plate and the sphere, expression of potantial of the sphere at time t is :

    Solution

  • Question 6
    4 / -1

    The Kinetic energy must an α-particle possess to split a deutron H2 whose binding energy is Eb = 2.2 MeV -

    Solution

  • Question 7
    4 / -1

    Assuming that about 20 MeV of energy is released per fusion reaction, 1H2 + 1H30n1 + 2He4, the mass of 1H2 consumed per day in a future fusion reactor of power 1 MW would be approximately

    Solution

  • Question 8
    4 / -1

    Nuclei of radioactive element A are produced at rate ' t2 ' at any time t. The element A has decay constant λ. Let N be the number of nuclei of element A at any time t. At time t = t0 is minimum. Then the number of nuclei of element A at time t = t0 is

  • Question 9
    4 / -1

    If nuclear charge is doubled in a hydrogen like atom, which of the following statement(s) are consistent with Bohr’s theory?

    Solution

  • Question 10
    4 / -1

    Ionization energy of a hydrogen-like ion B is less than that of hydrogen like ion A. Let r, u, E and L represent the radius of the orbit, speed of the electron, energy of the atom and orbital angular momentum of the electron respectively. In ground state
