Question

Alpha-particles that come closer to nuclei in Rutherford's alpha particle scattering experiment:

• A. are deflected more
• B. are deflected less
• C. make more collisions
• D. None of the above

Answer 1

Answer: (A)

In the $\alpha$-particle experiment as the alpha particles come closer to the nucleus it deflects more, because $\alpha$-particle and the nucleus both are positively charged. And positive charge repel each other and this electrostatic force is inversely squared proportional to the distance between $\alpha$-particle and nucleus.
Option 'A' is correct.
