Two identical photocathodes receive light of frequencies f1 and f2. If the velocites of the photo electrons (of mass m) coming out are respectively v1 and v2, then

View answer

Two trains each of length 50 m, are approaching each other on parallel rails. Their velocities are 10 m/s and 15 m/s respectively. In how many seconds they will cross each other?

View answer

In a photoelectric experiment a parallel beam of monochromatic light with power of 200 W is incident on a perfectly absorbing cathode of work function 6.25 eV. The frequency of light is just above the threshold frequency so that the photoelectrons are emitted with negligible kinetic energy. Assume that the photoelectron emission efficiency is 100%. A potential difference of 500 V is applied between the cathode and the anode. All the emitted electrons are incident normally on the anode and are absorbed. The anode experiences a force F = n x 10-4N due to the impact of the electrons. The value of n is __________. Mass of the electron me= 9 x10-31kg and 1.0 eV = 1.6 x10-19J. Correct answer is '24.00'. Can you explain this answer?
