Unformatted text preview: Discussion Question 2A P212, Week 2 Electric Field Lines 1 Electric fields are force fields produced by electric charges. They can extend throughout space, and influence other charges (and currents and magnetic fields, as you will discover later in the course). Electric Field Lines graphically represent electric fields. They show you the direction and relative magnitude of force that a test charge would feel in the field region. (a) The configuration at right shows some points around a positive charge Q . If a positive test charge q is placed at point A, at a distance r A from Q , calculate the magnitude of the force on the test charge in terms the given variables. |F A | = k qQ / r A 2 Draw the direction of the force with an arrow on the diagram. (b) Would the magnitude of the force be bigger or smaller if the charge was placed at points B,C, or D? Force would be bigger at B, smaller at C or D Draw the direction of these forces on the diagram with arrows, using the length of the arrows to...
