what happens when we rub both P.V.C. rod & plastic rod with silk and what happens when we rub both P.V.C. rod & plastic rod with wool ?
Asked by MOHAMMAD ISHAQUE | 3rd Dec, 2010, 12:00: AM
When wool is rubbed against a PVC (a type of plastic) strip, the PVC steals electrons from the wool because it has a greater attraction for electrons than wool does. The PVC strip ends up with a negative charge while the wool ends up with a positive charge. Since PVC is a good insulator, the charges stay where they are placed. They will remain there until someone handles the surface of the strip (grounding it) or until particles in the atmosphere steal the charge from it.
If we rub the Plastic Rod with Silk, Negative Charges will be transferred from Rod to the Silk. The Rod becomes Positively Charged.
Hope this helps.
