In Rutherford experiment, for head-on collision of a-particles with a gold nucleus, the impact parameter is

Options

  1. Aof the order of ( 10⁻¹⁰ ~m )
  2. Bzero
  3. Cof the order of ( 10⁻⁶ ~m )
  4. Dof the order of ( 10⁻¹⁴ ~m )

Correct answer

B. zero

Step-by-step solution

(B) For head on collision the impact parameter is zero as it retraces the path.
