Static Electricity Quiz

What is the primary characteristic of static electricity?

• It involves immobile charges on the surface of insulators.

• It involves moving charges within a conductor.

• It is the flow of electrons through a circuit.

• It is the movement of protons within a material.

Which subatomic particle is positively charged?

• Proton

• Neutron

• Electron

• Photon

What happens to an atom when it gains electrons?

• It becomes positively charged.

• It loses protons.

• It becomes negatively charged.

• It remains neutral.

What is the process called when electrons are transferred by rubbing two materials together?

• Charging by induction

• Charging by conduction

• Charging by radiation

• Charging by friction

In the context of static electricity, what role does friction play?

• It allows electrons to jump from one material to another.

• It prevents the movement of electrons.

• It neutralizes the charges on a material.

• It creates a magnetic field.

What is the primary function of an electroscope?

• To store electric charges

• To convert static electricity into current electricity

• To detect and measure electric charges

• To generate static electricity

What part of the electroscope is responsible for displaying the deflection caused by static charges?

• Insulator

• Gold leaf

• Glass window

• Metal cap

How can an electroscope be discharged?

• By shaking it vigorously

• By bringing a positively charged object into contact with it

• By bringing a negatively charged object close to it

• By exposing it to sunlight

What happens to the gold leaf in an electroscope when like charges are present?

• It attracts the metal cap.

• It changes color.

• It deflects due to repulsion.

• It remains stationary.

What is the result when a charged object is brought near the metal cap of an electroscope?

• The electroscope becomes magnetized.

• The charges spread to the plate and gold leaf.

• The electroscope loses its charge.

• The electroscope emits light.
