Conservation of Electric Charge

When a balloon is rubbed against a sweater, electrons are transferred from the sweater to the balloon. What type of charge does the balloon acquire?

• Positive charge

• Negative charge

• Neutral charge

• No charge is acquired

What fundamental principle states that the total electric charge within an isolated system remains constant?

• Coulomb's Law

• Ohm's Law

• Conservation of Electric Charge

• Faraday's Law

A charged amber rod is brought into contact with a neutral pith ball. Initially, the pith ball is attracted to the rod, but after contact, it is repelled. What is the most likely explanation for the repulsion?

• The pith ball became positively charged by induction.

• The pith ball became negatively charged by conduction.

• The amber rod lost all its charge.

• The pith ball became neutral again.

An uncharged aluminum can is attracted to both a positively charged glass rod and a negatively charged rubber rod. This phenomenon is best explained by:

• Conduction, where charges are transferred to the can.

• Grounding, which neutralizes the can.

• Polarization, where charges within the can redistribute.

• Magnetic induction, causing a magnetic field.
