    Penetrating power of X-rays depends on

    A)  current flowing in the filament

    B)  applied potential difference

    C)  nature of the target

    D)  All of the above

    Correct Answer: B

    Solution :

    Energy of X-rays = eV V = applied potential. Penetrating power of X-ray depends on their energy, and energy depends on applied potential. \[\therefore \] Penetrating power of X-ray depends on applied potential.
