MCQ
If an α-particle collides head-on with a nucleus, what is its impact parameter?
  • A
    Zero
  • B
    Infinite
  • C
    10-10 m
  • D
    1010 m

Answer

  1. Zero

Explanation:

The perpendicular distance between the path of a projectile and the center of the potential field is the impact parameter.

Therefore, for a head-on collision of the α-particle with a nucleus, the impact parameter is equal to zero.
