  • What happens when two insulators are rubbed together?
    Electrons are transferred between the materials
  • What charge does a material acquire when it loses electrons?
    The material becomes positively charged
  • What charge does a material acquire when it gains electrons?
    The material becomes negatively charged
  • How are the charges of two insulators after rubbing related?
    They are equal but opposite in charge
  • How do opposite charges interact?
    They attract each other
  • What happens when a negatively charged object is near a positively charged object?
    They attract each other
  • How do like charges interact?
    They repel each other
  • What occurs when two positively charged objects are near each other?
    They repel each other
  • Why do we feel an electric shock?
    Due to discharge of electrostatic charge
  • What is meant by 'earthing' an object?
    Connecting it to the ground to discharge
  • What happens during an electric shock?
    Electrons flow to even out the charge
  • Why does lightning occur?
    Due to electrostatic charge buildup in clouds
  • What happens when clouds discharge their electrostatic charge?
    It results in lightning
  • Why does a charged balloon stick to a wall?
    It attracts the wall's negative charges
  • What occurs to the charges in the wall when a charged balloon is near?
    Positive charges are repelled, creating attraction
  • How can a comb pick up paper pieces?
    The comb attracts oppositely charged paper particles
  • What happens when a comb is rubbed against hair?
    The comb gains an electrostatic charge
  • How does earthing remove excess charge?
    It provides a low resistance path for electrons
  • How is electrostatic charge used in paint spraying?
    It attracts paint to the object being painted
  • What is the benefit of electrostatic charge in paint spray?
    It reduces paint waste by spreading out
  • How does static electricity pose a danger when fueling cars?
    It can cause sparks that ignite fuel
  • What causes static charge buildup during fueling?
    Friction between pipes and fuel flow
  • How is the danger of static electricity during fueling resolved?
    By earthing the vehicle and pump
