What happens to silk and plastic when we rub them together?
When you rub the plastic rod (polyethylene terephthalate, glycol modified, or PETG) with the wool cloth, the rod charges negative. When you rub the glass rod with the silk, the rod charges positive.
What happens when you rub silk?
A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged.
What happens when you rub an acetate rod with a cloth?
An acetate rod is rubbed with a cloth duster, giving the acetate rod a net positive charge and the duster a net negative charge. We rub the two against each other resulting in a net positive charge for the acetate rod and a net negative charge for the duster.
What happens when you rub wool and silk?
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity.
What exactly happens when you rub silk against glass and what happens to the charge of each of these materials as a result explain why this happens?
When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons. Now the glass rod has 8 electrons and 10 protons which makes it positively charged. Silk has 9 electrons and 7 protons making it negatively charged.
How does rubbing an acetate rod with a cloth causes the rod and cloth to become charged?
When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod. If the rod is swapped for a different material such as acetate , electrons are rubbed off the acetate and onto the duster.
Is there a force of attraction between the acetate rod and cloth?
There is no force between the acetate rod and the cloth.
What happens when you rub acetate with wool?
The duster becomes positively charged. If a rod of cellulose acetate is rubbed the charge on it is positive. When amber is rubbed with fur the amber becomes negatively charged. All these things were neutral to start with, in other words they had equal numbers of positive and negative charges.
What happens when we rub glass rod with silk?
Solution: When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. Glass rod becomes positively charged and silk becomes negatively charged.
