Please answer Q5

10 Z 75 15 All dimensions in mm (NOTE: Please notice that the images and videos captured under the inverted microscope are 'flipped' of their left and right directions.) 1. Please express the separation gap (along y-direction) between the aluminum electrodes as a function of x. 2. Under the 20 Vpp driving voltage, please express the generated electric field strength as the rate of change of Vpp along the y-direction. Ideally, should this E change along y? And should alElay be zero in the ideal case? 3. What is Blox in the ideal case? 4. You may recognize that the edges of the aluminum electrodes are not perfectly straight (see above). Can you describe how such defect can affect Elex and CE@y? GOOOO 5. Once the AC driving voltage is on, you may see the polystyrene beads link up along the y-direction (see above). Please explain
