Electricidad: fuerza eléctrica y campos eléctricos

The video explains that objects with electric charge, like a comb, have an electric field surrounding them. This field extends outward and can interact with other objects, such as pulling papers towards the charged comb. The interaction between charged objects is known as electric force.

What is created around an object that has an electric charge?

• A sound wave

• An electric field

• A gravitational field

• A magnetic field

How does an electric field behave around a charged object?

• It extends inward

• It extends outward

• It disappears

• It remains static

What happens when a charged comb is brought near papers?

• The papers are pushed away

• The papers are pulled toward the comb

• The papers catch fire

• The papers remain unaffected

What is the force called that acts between charged objects?

• Electric force

• Gravitational force

• Nuclear force

• Magnetic force

Which of the following is an example of an object with an electric charge?

• A glass of water

• A plastic comb

• A wooden stick

• A metal spoon
