Final answer:
A car attracts dust right after it is polished due to charging by friction, where the car wax and car tires become charged with an opposite charge to the dust particles. This creates an attractive force between the charged object and the dust particles, causing them to stick to the car's surface.
Step-by-step explanation:
When a car is polished, it becomes charged due to a process called charging by friction. This means that when two materials come into contact and then separate, they can transfer some of their charges to each other.
In this case, when the car is polished, the car wax and car tires, which are insulators, can become charged with an opposite charge to the dust particles. This creates an attractive force between the charged object and the dust particles, causing them to stick to the car's surface.
It is important to note that charging by friction is different from electrostatic induction, which occurs when an electrically charged object polarizes another object, resulting in an attractive or repulsive force.
