An ink printer sprays droplets of ink onto a piece of paper to form text. An electric potential ofp millivolts ( mV) is used to control the horizontal impact distance, h, measured in micrometers
(um) from the target where positive or negative values of hrepresent distances to the right or
left of the target respectively. Without an electric potential,0 mV would be created and the
droplet would impact 100 u mto the left of the target. An electric potential producing
200 m Vallows the droplet to impact the target exactly. Which of the following graphs in the
ph-plane could represent this situation?
