An acetate rod is rubbed with a dry cloth. Both the rod and the cloth become charged as electrons move between them. The acetate rod becomes positively charged.
Which row correctly shows the direction of electron movement and the final charge on the cloth?
Direction of electron movement: From the rod to the cloth; Final charge on the cloth: Negative
Direction of electron movement: From the cloth to the rod; Final charge on the cloth: Negative
Direction of electron movement: From the rod to the cloth; Final charge on the cloth: Positive
Direction of electron movement: From the cloth to the rod; Final charge on the cloth: Positive
