positive charge
Explanation
## Step 1:The purpose of using a high-voltage grid in spray painting is to control the distribution of paint particles. The grid is used to charge the paint particles as they pass through it.## Step 2:To ensure that the paint particles are attracted to the object being painted, the grid must have a charge opposite to that of the paint particles. Typically, the paint particles are given a negative charge as they exit the spray gun.## Step 3:Since the paint particles are negatively charged, the grid must have a positive charge to attract and evenly distribute the negatively charged paint particles onto the object being painted.
