Question

The diagram shows the path of four $\alpha$-particles of the same energy being scattered by the nucleus of an atom simultaneously. Which path is not physically possible?

• A. $2$
• B. $3$
• C. $1$
• D. $4$

Answer 1

The correct option is D $4$

Nucleus and $\alpha$-particles are positively charged.

$\Rightarrow$ Force of interaction must be repulsive in nature.

$1,2$ and $3$ paths show repulsive nature, but $4^{\text{th}}$ path shows attractive nature.

Therefore, it is not possible.

Hence, option $\left(D\right)$ is the correct answer.
