Solved/QM-06004 :: Probability for electron being in non-classical region

Show that the probability that electron in  the ground state of hydrogen  atom will be found outside the classical region is $13e^{-4}$.  It is   given that the normalized radial wave function of the  electron,  in the ground state, is  $$ R_{10}({r}) = 2 \left(1\over a_0\right)^{3/2} \exp(-r/a_0) $$   where \(a_0=\frac{\hbar^2}{me^2}\) is the Bohr radius and the energy levels of H atom are given to be \(E_n= -\frac{e^2}{2a_0n^2}\)

 Inkjet Printer


If an ink drop has a mass of $50\times10^{-9}$g and is given a  charge of  $-200\times 10^{-15}$ C, find vertical displacement in an inkjet printer with 3keV deflection potential, 3mm plate separation and 15 mm deflection plate length. The nozzle ejects the drop with velocity 25 m sec$^{-1}$ and leaving edge of the deflection plate is at a distance 15 mm from the paper.
