Q27.In the Rutherford experiment, α-particles are scattered from a nucleus as shown. Out of the four paths, which path is not possible? (1) D (2) B (3) C (4) A
What This Question Tests
This question assesses the understanding of the repulsive electrostatic force between the positively charged alpha particles and the positively charged nucleus in Rutherford's experiment, which dictates that alpha particles must always curve away from the nucleus. An impossible path would show attraction or an unperturbed trajectory through the nucleus.
