In an inkjet printer,1 tiny drops of ink of inertia m are given a charge q and then fired toward the paper at speed v. they first pass between two charged plates of length l that create an uniform electric field of magnitude e between them. the field direction is perpendicular to the plates and to the initial path of the drops. the electric field deflects each drop from its initial horizontal path and is used to control what is printed on the paper ("steering" it to the right spot). (a) show (using kinematics) that the amount of vertical deflection is given by ∆y = 1 2 (q/m)(l/v) 2e. (b) for a drop of inertia 1.5 × 10−10 kg, an electric field strength of 1.2 × 106 n/c, a plate of length 10 mm, and a drop speed of 20 m/s, calculate the drop charge necessary to result in a deflection of 1.3 mm. how many excess or deficit electrons is this charge equivalent to? (c) are we justified in ignoring gravity here? explain and/or calculate.

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
