Assertion (A): An alpha particle is moving towards a gold nucleus. The impact parameter is maximum for the scattering angle of \(180^{\circ}\) .
Reason (R): The impact parameter in an alpha particle scattering experiment does not depend upon the atomic number of the target nucleus.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
(D) A is false but R is true.
