Determine how large is the E→ electric field in an inkjet printer if the mass of a dropplet m=8⋅10-10kg and the ink drops have an initial velocity of v0=30.0ms, and a charge of q=18nC. The drop is deflected upward a distance of Δy=3.00mm as the drop travels through the Δx=2.00cm long region between two charged plates. Neglect any effects of gravity on the motion of the drops.)
Hint 1: E=Fq
Hint 2: F=(m⋅ay)
Hint 3: y=a⋅t22
Hint 4: v0=Δx/t
