Mysteriously a charged particle moving with velocity v =v₀ entered the tube of Thomson's apparatus where the parallel metallic plates of length 5 cm along X axis are separated by 2 cm . Under the influence of a magnetic field B = (4.57 10⁻² k ) T , the particle is found to deflect by an angle of 5.7^ . When a potential of 2000 volt is applied between the two plates, the particle is found to move straight to the scree

Options

  1. Athe velocity v₀=2.19 10^6 ~m / s .
  2. Bthe charge to mass ratio of the particle is 9.58 10^7 C / kg .
  3. Cradius of the circular path in the magnetic field is 50 cm .
  4. Dthe particle is identified as a proton.

Correct answer

D. the particle is identified as a proton.
