In Millikan's oil drop experiment, the forces acting on the oil drop are?

Upon irradiation with radiation of a suitable wavelength on the cathode, the photocurrent produced was reduced to zero by applying a stopping potential of $2.63 \mathrm{V}.$ If the work function of the cathode is $4.3 \mathrm{eV},$ find the approximate wavelength of the radiation (in $\mathrm{nm}$)

If the wavelength of an electronic transition in ${\mathrm{He}}^{+}$ is $23 \mathrm{nm}$, the wavelength corresponding to same transition in hydrogen atom in $\mathrm{nm}$ is

The wavelength (in $\mathrm{nm}$) of an electron moving with a velocity of $812 \mathrm{m} {\mathrm{s}}^{-1}$(mass of electron $=9.1\times {10}^{-31} \mathrm{kg}$ and Plank's constant $=6.626\times {10}^{-34}\mathrm{Js}$) is approximately _______

The ratio of potential energy (PE) and total energy of an electron in a Bohr orbit of a hydrogen like atom is

de Broglie was awarded the Nobel Prize in the year

Both the position and exact velocity of an electron in an atom can not be determined simultaneously and accurately. This is known as

How many of the following orbitals have two angular and one radial nodes?

$3\mathrm{d}; 4\mathrm{d}; 5\mathrm{f}; 3\mathrm{p}$
