An electron beam can undergo defractio by crystals. Through what potential should a beam of electrons be accelerated so that its wavelength becomes equal to 1.45Å .

An electron beam can undergo diffraction by crystals. The potential of 'V' volt should a beam of electrons be accelerated so that its wavelength becomes equal to 1.0Å . The value of 'V' is Given: (h^(2))/(m_(e)xxe)=3xx10^(-18)J^(2)s^(2)kg^(-1)"coulomb"^(-1)

An electron beam accelerated from rest through a potential difference of 5000 V in vacuum is allowed to impinge on a surface normally. The incident current is 50 muA and if the electrons come to rest on striking the surface the force on it is

An electron beam accelerated from rest through a potential difference of 5000 V in vacuum is allowed to impinge on a surface normaly. The incident current is muA and if the electrons come to rest on striking the surface the force on it is:

An electron beam in an X-ray tube is acclerated through a potential difference of 50000 volts. These are then made to fall on a tungsten target The shortest wavelength of the X-ray emitted by the tube is
