Question

A particle of mass M at rest decays into two particles of masses m1 and m2, having non-zero velocities. The ratio of the de-Broglie wavelengths of the particles, lambda subscript 1 end subscript divided by lambda subscript 2 end subscript is

  1. m subscript 1 end subscript divided by m subscript 2 end subscript    
  2. m subscript 2 end subscript divided by m subscript 1 end subscript    
  3. 1.0    
  4. square root of m subscript 2 end subscript end root divided by square root of m subscript 1 end subscript end root    

The correct answer is: 1.0


    By law of conservation of momentum

    In an experiment of photo-electric effect, singly ionized ‘He’ is excited electronically to different energy levels. The emission spectra of the He hence produced is made incident on a photoelectric plate in the photo-cell. When He is excited to fourth energy level then the observed stopping potential of photo –cell is found to be five times the stopping potential when hydrogen is excited to third energy level. The work function of the material of the photo electric plate is
