Electric Fields

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force. It is represented by field lines that indicate the direction and strength of the force.

Front

How does distance affect electric field strength?

Back

The strength of the electric field decreases with increasing distance from the charge. Specifically, it is inversely proportional to the square of the distance from the charge.

Front

What happens to the electric field strength as two charged objects get closer?

Back

The electric field strength increases as the distance between two charged objects decreases.

Front

What is the direction of the electric field created by a positive charge?

Back

The electric field created by a positive charge points away from the charge.

Front

What is the direction of the electric field created by a negative charge?

Back

The electric field created by a negative charge points towards the charge.

Front

What does it mean when electric field lines are closer together?

Back

When electric field lines are closer together, it indicates a stronger electric field in that region.

Front

What does it mean when electric field lines are further apart?

Back

When electric field lines are further apart, it indicates a weaker electric field in that region.

Front

What is the effect on an electron placed in an electric field?

Back

An electron will accelerate in the direction opposite to the electric field, moving towards the positively charged plate.

Front

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

Back

The force experienced by a charge in an electric field is given by F = qE, where F is the force, q is the charge, and E is the electric field strength.

Front

What is the principle of superposition in electric fields?

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.
