Electrostatics

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 magnitudes of the charges and inversely proportional to the square of the distance between them.

Front

How can you increase the electric force of repulsion between two charges?

Back

You can increase the electric force of repulsion by increasing either charge or decreasing the distance between them.

Front

If the charge of one object is tripled, how does it affect the force between two charged objects?

Back

The force increases by a factor of three, according to Coulomb's Law.

Front

What happens to the force between two charges if the distance between them is doubled?

Back

The force decreases by a factor of four, as it is inversely proportional to the square of the distance.

Front

What is the electric field?

Back

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

Front

How do you determine the direction of electric field lines?

Back

Electric field lines point away from positive charges and toward negative charges.

Front

What does it mean if two charges are identical and placed in an electric field?

Back

Identical charges will experience the same magnitude of force when placed in the same electric field.

Front

What is the law of conservation of charge?

Back

The law of conservation of charge states that charge cannot be created or destroyed, only transferred from one object to another.

Front

What is the relationship between electric field strength and force on a charge?

Back

The force on a charge in an electric field is equal to the charge multiplied by the electric field strength (F = qE).

Front

What is the significance of the sign of a charge?

Back

The sign of a charge indicates whether it is positive or negative, affecting how it interacts with other charges.
