Figure shows an assembly of deflecting plates A and B ofan ink-jet printer which causes moving ink droplets to deflect at desired displacements by continuously varying electric field between the plates. An ink drop with a mass `m = 1.3 xx 10^(-10)kg` and a negative charge of magnitude `q = 1.5x x 10^(-13)C` enters the region between the plates, initially moving along the x-axis with speed `v_(x), = 18m//s`. The length of plates is `L = 1.6cm`. The plates are connected with a varying voltage and thus produce an electric field at all points between them. Assume that field `vec(E)` for some duration is constant and it is acting in downward direction as shown and has a magnitude of `E = I .4 xx 10^(6) N//C`, find the vertical deflection of the drop at the far edge ofthe plate? As the gravitational force on the drop is very small relative to the electrostatic force acting on the drop, it can be neglected for this analysis. `[6.4 xx 10^(-4)m]`
