Alpha-particle that come closer to nuclei: - Vidyadip

MCQ

Alpha-particle that come closer to nuclei:

✓
Are deflected more
B
Are deflected less
C
Make more collisions
D
None

✓

Answer

Correct option: A.

Are deflected more

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.
