Physics 2018 JAMB Past Questions - Question 3: Which of the following is true of an electrical charge?

Correct Answer

D

Explanation

An electrical charge is a fundamental property of matter. It can be positive or negative, and it is responsible for the electromagnetic force. The following statements are true about electrical charges:

1. Like charges repel each other: Two objects with the same type of charge (both positive or both negative) will push each other away.

2. Opposite charges attract each other: Two objects with different types of charge (one positive and one negative) will be pulled towards each other.

3. Charges can be transferred: Electrons can be transferred from one object to another, resulting in a net charge on each object.

4. Charges can be quantized: The charge of an object is always a multiple of the elementary charge, which is the charge of a single electron or proton.

5. Charges create electric fields: Charged objects create electric fields around them, which can exert forces on other charged objects.

It's important to note that these statements describe the behavior of electrical charges based on our current understanding of electromagnetism.
