Electric Fields

Front

What is an electric field?

Back

An electric field is a region around a charged particle where a force would be exerted on other charged particles.

Front

How is the strength of an electric field represented visually?

Back

The strength of an electric field is represented by field lines; closer lines indicate a stronger field, while further apart lines indicate a weaker field.

Front

What happens to the electric field as you move away from a point charge?

Back

The electric field strength decreases as you move further away from a point charge.

Front

What is the direction of electric field lines for a positive charge?

Back

Electric field lines point away from a positive charge.

Front

What is the direction of electric field lines for a negative charge?

Back

Electric field lines point towards a negative charge.

Front

What does it mean if an object is negatively charged?

Back

An object is negatively charged if it has more electrons than protons.

Front

What does it mean if an object is positively charged?

Back

An object is positively charged if it has more protons than electrons.

Front

What is the relationship between electric field strength and distance from the charge?

Back

Electric field strength is inversely proportional to the square of the distance from the charge.

Front

What is a uniform electric field?

Back

A uniform electric field is one where the electric field strength is constant in magnitude and direction.

Front

What is the formula for calculating electric field strength (E)?

Back

E = F/q, where E is the electric field strength, F is the force experienced by a charge, and q is the magnitude of the charge.
