\( \alpha \)-particles are scattered by the gold nucleus but not by the electrons. It is, because
(a) electrons are much massive than \( \alpha \)-particle
(b) \( \alpha \)-particles are massive than electrons but only about \( 2 \% \) massive for a gold nucleus
(c) \( \alpha \)-particles are nearly of same mass or that of nucleus
(d) \( \alpha \)-particles are positively charged
\( \mathrm{P} \)
