What is Amber? What happens when it is rubbed with fur?
Dear Student ,
If a rod of cellulose acetate is rubbed the charge on it is positive. .When amber rubbed with fur the amber becomes positively charged. When glass is rubbed with silk the glass becomes negatively charged. All these things were neutral to start with, in other words they had equal numbers of positive and negative charges.
