Atracción electrostática

The video tutorial explains the existence of electric charges with different signs, highlighting that like charges repel and opposite charges attract. It introduces Coulomb's law, which states that the force between two charges is proportional to the product of their intensities and inversely proportional to the square of the distance between them.

What is the nature of electric charges?

• They do not exist.

• They are always negative.

• They can be of different signs.

• They are always positive.

What happens when two charges of the same sign are near each other?

• They attract each other.

• They become neutral.

• They have no effect on each other.

• They repel each other.

According to Coulomb's law, what is the relationship between force and charge intensity?

• Force is inversely proportional to charge intensity.

• Force is directly proportional to charge intensity.

• Force is unrelated to charge intensity.

• Force is equal to charge intensity.

How does the distance between two charges affect the force between them according to Coulomb's law?

• Force is inversely proportional to the distance.

• Force is inversely proportional to the square of the distance.

• Force is directly proportional to the distance.

• Force is unaffected by the distance.

Which of the following best describes Coulomb's law?

• It states that force is proportional to the distance between charges.

• It states that force is proportional to the product of the charges and inversely proportional to the square of the distance.

• It states that force is inversely proportional to the product of the charges.

• It states that force is directly proportional to the square of the distance.
