To determine which option is correct, we need to understand the fundamental principles of electric charges.
Electric charges can be positive or negative, and like charges repel each other while opposite charges attract each other. This behavior is described by Coulomb's Law, which states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Now let's look at each option:
A. Attract each other: This is actually true for electric charges that are different. Opposite charges attract each other, so option A is not correct.
B. Repeal each other: "Repeal" is likely a typo, but if it is meant to be "repel," then this is true for charges that are the same. Like charges repel each other, not charges that are different. Therefore, option B is not correct.
C. Exist in pair: Electric charges can exist as single charges or in pairs, meaning there can be one positive charge and one negative charge. However, this is not exclusive to charges that are different. So, option C is not a definitive answer to our question.
D. Do not interact: This option is not correct because charges interact with each other through the electromagnetic force, either by attracting or repelling each other. Charges do interact with each other, even if they are different.
Based on these explanations, the correct answer is option A: Electric charges that are different attract each other.
