Two parallel discs are connected by a rigid rod of length L =0.5 ~m centrally. Each disc has a slit oppositely placed as shown in the figure. A beam of neutral atoms are incident on one of the discs axially at different velocities v , while the system is rotated at angular speed of 600 rev/second so that atoms only with a specific velocity emerge at the other end. Calculate the two largest speeds (in meter/second) of

Options

  1. A75,25
  2. B100,50
  3. C300,100
  4. D600,200

Correct answer

D. 600,200

Step-by-step solution

Time gap between two disc should t = , 3 , 5 array l V ₁= 0.5 600 2 600 ~m / s V ₂= 0.5 3 / 600 2 200 ~m / s array
