In the Rutherford's alpha scattering experiment, as the impact parameter increases, the scattering angle of the alpha particle.

Options

  1. Aremains the same
  2. Bis always 90^
  3. Cdecreases
  4. Dincreases

Correct answer

C. decreases

Step-by-step solution

In the Rutherford's -scattering experiment, impact parameter (b) and scattering angle are related as, aligned b & = 1 4 ₀ z e^2 2 ( 1 2 m v^2 ) b & 2 aligned Thus, with the increase of impact parameter (b) , 2 increases. It is possible only when will decrease.
