Draw one straight line from each electrostatic application to its correct description.
| Electrostatic application | Description |
|---|---|
| Electrostatic dust precipitator | Removes excess charge safely to the ground to prevent explosive sparks. |
| Rubbing a balloon on a synthetic jumper | Attracts charged toner particles to form a dry image on paper. |
| Earthing a fuel tanker during refuelling | Uses a charged grid to make waste particles stick to oppositely charged collector plates. |
| Photocopier drum | Causes transfer of electrons by friction, allowing an insulator to stick to a wall. |
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.
