There are two types of electric charges. Which are they?

• A. Neutral and Charged
• B. Positive and Negative
• C. Static and Dynamic
• D. Conducting and Insulating

Answer: (B)

Electric charge comes in two signs: positive and negative. Protons carry positive charge and electrons carry negative charge, so objects are charged when they have an excess or deficit of electrons; when there’s no net excess or deficit, the object is neutral. The two signs are fundamental because charges of opposite signs attract and like signs repel, and the magnitude of a charge is a multiple of the elementary charge. The other options describe states or material properties rather than the signs of charge: neutral vs charged is about having zero net charge, static vs dynamic refers to whether the charge is at rest or moving, and conducting vs insulating describes how easily charge flows in a material.
