Q. The ink drops have a mass = 1.0×10-11 each and leave the nozzle and travel horizontally toward the paper at velocity = 22. The drops pass through a charging unit that gives each drop a positive charge by causing it to lose some electrons. The drops then pass between parallel deflecting plates of length = 2.05, where there is a uniform vertical electric field with magnitude = 7.80×10^4.

If a drop is to be deflected a distance = 0.250 by the time it reaches the end of deflection plate, what magnitude of charge must be given to the drop? Suppose that the density of the ink drop is 1000 and ignore the effects of gravity.

State your answer numerically in coulombs.
