[QUE/EM-01002] --- EM-PROBLEM

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.Source [Kraus p117]
