A sprayer produces positively charged insecticide droplets near an initially neutral conducting model leaf. The leaf is insulated from Earth. The droplets do not touch it.
Which explains the initial attraction?
Electrons in the leaf move away from the droplets; attraction to the farther negative region is greater.
Protons in the leaf move towards the droplets; attraction to the nearer positive region is greater.
Protons in the leaf move away from the droplets; attraction to the farther positive region is greater.
