G8 Quiz - Static Electricity

If two charges repel each other, the two charges must be

• Positive and neutral

• Positive and negative

• positive and neutral

• negative and negative

An object becomes charged when the atoms in the object gain or lose

• electrons
• protons
• neutrons
• all of the above

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

• friction.

• induction

• polarization

• conduction.

Charging by ____ occurs when electrons are transferred from one object to another by direct contact.

• reduction
• induction
• conduction
• friction

An object becomes postiively charged when which of the following occurs?

• loses electrons
• gains electrons
• loses protons
• gains neutrons

Bending water with a charged balloon is an example of what type of charging (charging an object without touching)

• friction

• induction

• conduction

The loss of static electricity as electric charges move from one object to another.

• Electric field
• Electric force
• static electricity
• static discharge

The negatively charged balloon is brought near the two cans. What happens?

• The negative charges in Can B move towards the balloon
• The negative charges in Can A move away from the balloon
• The positive charges in Can B move towards the balloon
• The positive charges in Can A move away from the balloon

Which of these is the best definition of polarization?

• The object gains a positive or negative charge from another object.
• The charges in a neutral object separate due to a nearby charged object.
• Charges on a neutral object jump off onto a charged object due to attraction of opposite charges.
• Two objects attract each other because they are both charged.

A positively charged balloon is brought near a neutral conducting sphere as shown below. While the balloon is near, the sphere is touched (grounded).

At this point, there is a movement of electrons. Electrons move ____ .

• into the sphere from the ground (hand)

• out of the sphere into the ground (hand)

• into the sphere from the balloon

• out of the sphere into the balloon

• from the ground through the sphere to the balloon
