Questions and Answers

Which statement accurately describes the nature of electric charges?

Like charges repel, and opposite charges attract. (correct)

All charges attract each other, regardless of their nature.

Electric charges can be created or destroyed under certain conditions.

Like charges attract, and opposite charges repel.

What is the principle of conservation of electric charge?

Electric charge is always constant and cannot be changed.

Electric charge can be transferred from one body to another, but not created or destroyed. (correct)

Electric charge can be created or destroyed through certain processes.

Electric charge can spontaneously appear or disappear in isolated systems.

What is the relationship between the electric force (Fe) and the distance (r) between two point charges, according to Coulomb's law?

Fe is inversely proportional to r.

Fe is directly proportional to r.

Fe is inversely proportional to the square of r. (correct)

Fe is independent of the distance between the charges.
