Which type of electric charge repels other positive charges and attracts negative charges?

A positive electric charge is characterized by its ability to repel other positive charges while attracting negative charges. This behavior is fundamental to the nature of electric charges, which exist in two types: positive and negative. The interaction between these charges follows Coulomb's law, which states that like charges repel each other and opposite charges attract.

When two positive charges are brought close to each other, they exert a force that pushes them apart. Conversely, when a positive charge is near a negative charge, there is an attractive force that draws them together. Understanding the principles of electric forces and charge interactions is crucial in exploring electric fields, circuits, and other related concepts in electricity.

The other options do not exhibit this behavior. A neutral electric charge has no net charge and therefore does not exert any electric force on other charges. A negative electric charge would repel other negative charges and attract positive charges, which is the opposite of what is being asked. "Superficial charge" is not a commonly recognized term in electrostatics and does not accurately describe any type of charge interaction.
