In the ground state of hydrogen atom, electron absorbs 1.5 times energy than the minimum energy \( (2.18 \times 10^{-18} J)\) to escape from the atom. The wavelength of the emitted electron (in m) is \((m_e = 9 \times 10^{-31} kg)\)
The de Broglie wavelength of a particle of mass 1 mg moving with a velocity of \( 10 \) ms\(^{-1}\) is (h = \( 6.63 \times 10^{-34} \) Js)
Correct set of four quantum numbers for the valence electron of strontium (Z = 38) is
The de Broglie wavelength of an electron with kinetic energy of \( 2.5 \) eV is (in m): \[ (1 \text{ eV} = 1.6 \times 10^{-19} \text{ J}, \quad m_e = 9 \times 10^{-31} \text{ kg}) \]
If the position of the electron was measured with an accuracy of \( \pm 0.002 \) nm, the uncertainty in the momentum of it would be (in kg ms\(^{-1}\)) (\( h = 6.626 \times 10^{-34} \) Js):
A golf ball of mass ‘m’ has a speed of 50 m/s. If the speed can be measured within accuracy of 2\%, the uncertainty in the position is
If \(\Delta x\) is the uncertainty in position and \(\Delta v\) is the uncertainty in velocity of a particle are equal, the correct expression for uncertainty in momentum for the same particle is
