What is the definition of electrostatic force?

• The force that opposes motion between two surfaces.

• The gravitational pull between two masses.

• The magnetic attraction between two magnets.

• The force between charged objects due to their electric charges.

What are the two types of electric charges?

• Positive and Electric

• Negative and Neutral

• Positive and Negative

• Positive and Neutral

What happens when two objects with the same charge are brought close together?

• The objects repel each other.

• The objects explode upon contact.

• The objects become neutral.

• The objects attract each other.

Name one application of electrostatics in everyday life.

• Hair dryers

• Toasters

• Photocopiers

• Electric kettles

How does electrostatic force affect dust particles?

• Electrostatic force only affects larger particles, not dust.

• Electrostatic force has no effect on dust particles' movement.

• Electrostatic force causes dust particles to become charged, leading to attraction, clumping, and altered movement.

• Electrostatic force repels dust particles, causing them to scatter.

What is the charge of a proton?

• +2 elementary charge

• 0 elementary charge

• +1 elementary charge

• -1 elementary charge

What is the charge of an electron?

• +1 elementary charge

• 0 elementary charge

• -2 elementary charges

• -1 elementary charge

Can electrostatic force be observed in nature? Give an example.

• Electrostatic force is only found in man-made devices.

• Electrostatic force cannot exist in a vacuum.

• An example of electrostatic force is ocean waves.

• Yes, electrostatic force can be observed in nature; an example is lightning.

What is the role of electrostatics in a photocopier?

• Electrostatics helps in the paper feeding process.

• Electrostatics is used to attract toner to the photoconductive drum and paper in a photocopier.

• Electrostatics is responsible for the color mixing of toner.

• Electrostatics is used to cool the photocopier components.

How do lightning strikes relate to electrostatic force?

• Lightning is a result of chemical reactions in the atmosphere.

• Lightning strikes are a result of electrostatic forces causing a discharge of electricity.

• Lightning strikes are caused by magnetic fields.

• Electrostatic forces have no effect on weather patterns.
