(2) Electric force between two positive charges Drag the sensor to all the locations marked with "x" in the following graph - Figure 2. For each location, (a) draw the red arrow in proper direction and length and (b) record the electric field value (9.29 V/m in the example). X * +1 nC + -1 nC * 0.0 deg 9.29 V/m Sensors Electric Field Figure 2-Record of the interaction between two positive charges Direction only Voltage Values Grid e aov Answer the following questions after finishing the activity: (a) Is the force between two positive charges always point towards or away from each other? What does that mean? (b) How does the relative strength (magnitude) of the force vary? The father they are apart, the stronger or the weaker the force? For example, what happens to the magnitude of the force when the distance between the two charges doubles, does the force stay the same, doubled, quadrupled, halved, or quartered? (3) Electric force between a positive charge and a negative charge Now replace the "red" positive charge by a "blue" negative charge at the center of the screen.

What does that mean? (b) How does the magnitude of the force vary with the distance between the two charges? When the distance between the two charges halves, does the force stay the same, doubled, quadrupled, halved, or quartered? (c) The amounts of charges involved in the above two simulations (Figure 1 and Figure 2) are the same. For the same sensor location, are the magnitudes of the recorded force in both graphs about the same or significantly different? (d) Check what happen to the force if you double the amount of the negative charge (simply by dragging and dropping another negative charge in the same location). Does the force stay the same, doubled, quadrupled, halved, or quartered?
