Draw one straight line from each electrostatic phenomenon or application to its correct description.
| Electrostatic phenomenon or application | Description |
|---|---|
| Electrostatic paint spraying of a car panel | Charges polar water molecules by induction, causing them to bend towards the charged object without touching it. |
| Rubbing an acetate rod with a dry cloth | Forces similarly charged liquid droplets to repel each other and cover the earthed target object evenly. |
| Wearing an antistatic wrist strap when handling microchips | Provides a path to safely discharge static buildup and protect delicate integrated circuits from static discharge. |
| Deflecting a thin stream of tap water with a charged plastic comb | Causes a transfer of electrons via friction, leaving the insulator with a net positive charge. |
47 exam-style questions on Edexcel GCSE Physics 11.1 Charging by friction, covering 11.1.1 Charging insulators by friction, 11.1.2 Forces between charges, 11.1.3 Electrostatic phenomena, and 11.1.4 Earthing and removing charge. Each one has a worked solution and a mark scheme showing where the marks go.
