Vedclass · Answer

(A) In the $\alpha$-particle scattering experiment,as the $\alpha$-particles come closer to the nucleus,they are deflected more. This is because both the $\alpha$-particle and the nucleus are positively charged. The positive charges repel each other,and according to Coulomb's law,this electrostatic force of repulsion is inversely proportional to the square of the distance between the $\alpha$-particle and the nucleus $(F \propto \frac{1}{r^2})$. Therefore,as the distance $(r)$ decreases,the force of repulsion increases,leading to a greater deflection.
