5E [2] - Electricity

Front

What is the magnitude of electric potential at an infinite distance?

Back

0

Front

What do electric field lines indicate?

Back

The direction of the force on a test positive charge.

Front

If a balloon has fewer positive charges than negative charges, how is it charged?

Back

Negatively charged.

Front

At which point is the electric field the weakest when field lines are further apart?

Back

Point C.

Front

What happens to the electric force if each of the charges doubles?

Back

The electric force quadruples.

Front

What is electric potential?

Back

The amount of work done per unit charge to move a charge from a reference point to a specific point in an electric field.

Front

Define electric field. How is it represented?

Back

An electric field is a region around a charged object where other charged objects experience a force. It is represented by field lines.

Front

What is the relationship between charge and electric force according to Coulomb's Law?

Back

The electric 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

What does it mean if electric field lines are dense?

Back

It indicates a stronger electric field.

Front

What is the significance of the direction of electric field lines?

Back

They point away from positive charges and toward negative charges, indicating the direction a positive test charge would move.
