At a plant nursery, an electrostatic sprayer applies liquid feed to seedlings. Every liquid-feed droplet is negatively charged as it leaves the nozzle. The seedling leaves behave as though positively charged.
Which pair of observations should occur as the spray approaches the leaves?
The droplets spread apart and curve away from the leaves
The droplets move together and curve towards the leaves
The droplets move together and curve away from the leaves
The droplets spread apart and curve towards the leaves
