Electric Fields Review

Front

What are electric field lines?

Back

Electric field lines are invisible lines that represent the direction and strength of an electric field. They show how a positive test charge would move in the field.

What happens to a negatively charged object when a positively charged object is brought near it?

Back

The negatively charged object will experience an attractive force towards the positively charged object.

Front

What is the relationship between charged objects and electric fields?

Back

Charged objects create electric fields around them, which can exert forces on other charged objects without direct contact.

Front

What do field lines indicate about the strength of an electric field?

Back

The density of field lines indicates the strength of the electric field; closer lines mean a stronger field.

Front

What is the effect of two like charges (both positive or both negative) on each other?

Back

Like charges repel each other, causing a force that pushes them apart.

Front

What is the effect of two opposite charges (one positive and one negative) on each other?

Back

Opposite charges attract each other, causing a force that pulls them together.

Front

What is an electric field?

Back

An 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 towards negative charges.

Front

What is the significance of the term 'force' in the context of electric fields?

Back

In electric fields, 'force' refers to the push or pull that charged objects exert on each other without touching.

Front

What happens to the electric field lines between two negatively charged objects?

Back

The electric field lines between two negatively charged objects will repel each other, indicating a repulsive force.
