Imagine that two charged rods are held together as shown and a charged pith ball is placed at point P.
Predict whether the rod farther from point P would exert an electric force on the pith ball. Explain.
Check your prediction by placing a charged pith bail al point P near two charged rods and then slowly moving one rod away from the other. Describe your observations and discuss with your partners whether your results from this experiment support your prediction.

- What direction would the force point on a test charge placed between parallel plates with one connected to a negative terminal of the battery while another is connected to the positive terminal of a battery? What about on either side of the parallel plates? Explain in terms of force. For this question, I assume the test charge is positive and that the force would point in the direction of the electric field (high to low toward the negatively charged plate). If placed outside of the positive plate, I assume the force would travel in the same direction as the E-Field (high to low). If on the other side of the negative plate, wouldn't the force travel opposite to the E-field lines?arrow_forwardI need question 4 from thisarrow_forwardTwo negatively-charged objects are located on the x-axis equally disstant from the origin as shown.
