The ink drops have a mass m = 1.00×10^−11 kg each and leave the nozzle and travel horizontally toward the paper at velocity v = 23.0 m/s . the drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. the drops then pass between parallel deflecting plates of length d0 = 1.80 cm , where there is a uniform vertical electric field with magnitude e = 8.20×10^4 n/c if a drop is to be deflected a distance d = 0.290 mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? assume that the density of the ink drop is 1000 kg/m^3
