An acetate rod is rubbed with a dry cloth.
The rod and the cloth both become charged as electrons move between them.
The rod becomes positively charged.
Which option correctly describes the direction of electron movement and the final charge on the cloth?
Electron movement: from rod to cloth; final charge on cloth: negative
Electron movement: from cloth to rod; final charge on cloth: negative
Electron movement: from rod to cloth; final charge on cloth: positive
Electron movement: from cloth to rod; final charge on cloth: positive
