3. Which of the following diagrams represent the field of force around a negative charge? c) b) 4. d) At which point (or points) is the electric field zero N/C for the two point charges shown on the x-axis? +49 -2q x a) The electric field is zero somewhere on the x axis to the right of the -2q charge. b) The electric field is zero somewhere on the x axis to the left of the +4q charge. c) The electric field is zero at two points along the x axis; one such point is to the right of the -2q charge and the other is to the left of the +4q charge. d) The electric field is zero somewhere on the x axis between the two charges, but this point is nearer to the -2q charge. e) The electric field is never zero in the vicinity of these charges. 5. Four point charges are held fixed at the corners of a square as shown in the figure. Which of the five arrows shown below most accurately shows the direction of the net force on the charge -Q due to the presence of the three other charges? -2Q -2Q +Q (b) 45° (d) > 45° 45°
