According to the Heisenberg's Uncertainty principle, the value of $\Delta \mathrm{b} . \Delta \mathrm{x}$ for an object whose mass is $10^{-6} \mathrm{~kg}$ is $\left(\mathrm{h}=6.626 \times 10^{-34} \mathrm{Js}\right)$

The energy associated with first orbit of $\mathrm{He}^{+}$ is

The number of protons, neutrons and electrons in the ion $${ }_{16}^{32} \mathrm{~S}^{2-}$$ respectively are

If wavelength of photon is $$2.2 \times 10^{-11} \mathrm{~m}$$ and $$h=6.6 \times 10^{-34} \mathrm{~J} \mathrm{~s}$$, then momentum of photon
