Question 1: At each point indicated by an , draw the individual electric field vectors due to the two positive charges, labeling which is which. In a different colour, draw the net electric field vector at each point Open the Internet Explorer and use the following link: http://www.compadre.org/Physlets/ X A electromagnetism Question 2: Set up the configuration of two positive charges shown below and sketch the electric field lines into the diagram provided. Are these field lines consistent with your prediction in Question 1? Question 3: Now add another charge halfway between the two, as in the diagram below, and sketch the electrifield lines. Question 4: Now add two more charges into the two gaps, as in the diagram below, and sketch the electric field lines. Question 5: What do you notice about the electric field above and below the line of charges as the number of charges increases? Do electric field lines ever cross? Explain how you know using the idea of superposition. Question 6: What would you expect the electric field to look like for a string of positive charges without any spacing? Sketch this in the diagram below and verify using the applet. DDDDDDD Q Q Q Q Q Q DDDDD
