Kevin connect the car body to the negative terminal of the power supply. He forget to connect the paint gun to the positive terminal.

The paint does not spray evenly over the car.

Explain why.

Ohhh ive seen this question! It was because the paint will not be positively charged and therefore not charged. If it is not charged then when the pant is put it wuld be uneven because there wuld be no repulsion between the similar charges, and therefore the paint wont be repelled then it wont have a level coating. Sorry if it is a bad explanation but iam very sure it is due to repulsion between similar charges!
