During the manufacturing of high-purity polymer films, a polyethylene sheet is passed over a nylon roller as shown in the diagram below.
Due to friction at the contact surface, the polyethylene sheet becomes negatively charged, while the nylon roller becomes positively charged.
Which statement correctly explains the electrostatic process occurring between the sheet and the roller?
Protons are transferred from the polyethylene sheet to the nylon roller.
Electrons are transferred from the nylon roller to the polyethylene sheet.
Electrons are transferred from the polyethylene sheet to the nylon roller.
Protons are transferred from the nylon roller to the polyethylene sheet.
