Electrostatics Review

Front

What do you call the process of charging a conductor by bringing it near another charged object?

Back

Induction is the process of charging a conductor without direct contact, by bringing it near another charged object.

Front

Label the charges respectively: +; -

Back

This represents a positive charge and a negative charge.

Front

A 0.20 kg pith ball has a charge of 3.6 C. What electric field, pointing upwards, will cause the pith ball to remain motionless?

Back

The electric field required is 0.55 N/C.

Front

What is the unit for Electric Force?

Back

The unit for Electric Force is Newton.

Front

Label the charges respectively: +; +

Back

This represents two positive charges.

Front

What is the principle of superposition in electrostatics?

Back

The principle of superposition states that the total electric field created by multiple charges is the vector sum of the electric fields created by each charge individually.

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects, 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 the formula for calculating electric field (E)?

Back

The electric field (E) is calculated using the formula E = F/q, where F is the force experienced by a charge q.

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge (e.g., metals), while insulators do not allow charge to flow easily (e.g., rubber, glass).

Front

What is electric potential energy?

Back

Electric potential energy is the work done to move a charge within an electric field, measured in joules.
