Question
Charge an acrylic rod by nabbing it with wool. Obtain a small pith ball attached to an insulating thread. Touch the ball to the charged rod and observe the behavior of the ball after it touches the rod. Is the ball charged after it touches the rod? If so does the ball have the same sign charge as the rod or the opposite sign charge? Explain how you can tell. B. Hold the charged rod horizontally. Use a charged pith ball to explore the region around the rod. On the basis of your observations, sketch a vector to represent the net electric force on the ball at each of the points marked by an "x". Is all of the charge on the rod located at a single point? (e.g., Is all the charge at the tip of the rod? At the middle?) Explain how you Top view can tell. On the basis of the vectors you have drawn, is it appropriate to consider the charged rod as a point charge? Explain. C. 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 ball at 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.Explanation / Answer
A. As the ball came into contact with the rod suppose the rod is having negatively charged so the near surface of ball due to electo static induction it will induce positive charge and the opposite far surface of ball induced negatively charge so ball will be attracted towards rod.
B.
