Question1
The ink drops have a mass = 1.00×10-11 each and leave nozzle and travel horizontally toward the paper at velocity = 23.0. The drops pass through a charging unit that gives each drop a positive charge by causing it to lose some electrons. The drops after that pass between parallel deflecting plates of length = 1.85, where there is a uniform vertical electric field with magnitude = 7.80×104.
Question2
If a drop is to be deflected a distance = 0.340 by the time it reaches the end of deflection plate, what magnitude of charge must be given to the drop? Imagine that the density of the ink drop is 1000, and ignore the effects of gravity.State the answer numerically in coulombs.
Question3
