AP Physics 2: Electrostatics and Charging

Front

What is the distribution of charge on a solid conducting sphere that is given a positive charge Q?

Back

The charge Q is uniformly distributed on the surface of the sphere only.

Front

Why does a plastic strip become positively charged when rubbed with cotton?

Back

The plastic strip loses electrons to the cotton during the charging process.

Front

What happens to like charges and opposite charges?

Back

Like charges repel each other, while opposite charges attract each other.

Front

If two charges (-80 μC and +100 μC) are arranged on the x-axis, what is the net force on the +100 μC charge?

Back

The net force on the +100 μC charge is 8.0×10^4 N to the left.

Front

What is the characteristic of electrical conductors?

Back

Electrical conductors allow electrons to flow through them.

Front

What is electrostatics?

Back

Electrostatics is the study of electric charges at rest and the forces and fields associated with them.

Front

What is the principle of conservation of charge?

Back

The principle of conservation of charge states that the total electric charge in an isolated system remains constant.

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge, while insulators do not allow charge to flow easily.

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two point charges, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.
