Material Science PHY407 Lab #25. How do you determine the total horizontal and the total vertical components of theresultant force?6. Will specifying the strength alone be sufficient to describe the resultant force? If not,what else is required and how would you do it?7. What can you conclude about the initial motion of the charged particle that issubjected to the total force in the activities above?Investigation 3-Electric fieldsPrediction 3.1:Draw the electric field lines (represented by { } to indicate smaller field and longer lines{ } to indicate stronger field) around the charged particle at the center of the grid foreach of the cases in Figure 3.1.Case1PredictionObservationCase2Figure 3.1a Figure 3.1aCase3Figure 3.1b Figure 3.1bCase4Figure 3.1c Figure 3.1cFigure 3.1d Figure 3.1dActivity 3.1:Configure the charges in the PhET simulation (Charges-and-Field). Draw the field lines youobserved for each of the cases in Figure 3.1.Created by Dr. JJ, FSG, UiTM Shah Alam Page 8 of 17 Last updated 17 th Jan 2010
