Consider the hypothetical situation where the azimuthal quantum number, $\mathcal{l}$, takes values $0, 1, 2, \dots \dots ..\mathrm{n} + 1$. Where n is the principal quantum number. Then, the element with atomic number:

Given below are two statements :
Statement I : Rutherford's gold foil experiment cannot explain the line spectrum of hydrogen atom.

Statement II : Bohr's model of hydrogen atom contradicts Heisenberg's uncertainty principle.

In the light of the above statements, choose the most appropriate answer from the options given below:

The kinetic energy of an electron in the second Bohr orbit of a hydrogen atom is equal to $\frac{{\mathrm{h}}^2}{\mathrm{x} {\mathrm{ma}}_0^2}.$ The value of $10 \mathrm{x}$ is (${\mathrm{a}}_0$ is radius of Bohr's orbit)

(Nearest integer)

A ball weighing $10 \mathrm{g}$ is moving with a velocity of $90 \mathrm{m} {\mathrm{s}}^{-1}.$ If the uncertainty in its velocity is $5\%$, then the uncertainty in its position is _  $\times {10}^{-33} \mathrm{m}.$ (Rounded off to the nearest integer)
