Question

When spray is applied to a car, the paint has a negative charge and the surface of the car has a positive charge. Some processes use a negatively charged paint and a grounded object. Explain why this also works.

Answer 1

Based on the properties electrically charged particles, we have that unlike charges attract and like charges repel each other. In order for proper application of an electrostatically negatively charged paint to be properly applied on the metal body surface of a vehicle, require that for attraction, the surface of the vehicle should be grounded and positively charged so as to effectively attract the negatively charged paint particles as it exits the nozzle, to form a strong attachment with the positively charged surface of the vehicle
