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. |
