Three objects are brought close to each other, two at a time. When objects A and B are brought together, they repel. When objects B and C are brought together, they also repel. Which of the following are true? a. additional experiments must be performed to determine the signs of hte cahrges.
b. objects A and C possess charges of the samesign.
c. one object is neutral.
d. objects A and C possess charges of the oppostite sign.
e. all three objects possess charges of the same sign.

option (e) = all three objects possess charges of the same sign.

Explanation:

To understand this particular problem or question, one has to take each point from the question/problem above with care;

=> "Three objects are brought close to each other, two at a time. "

Deduction: Only two are brought together at a time.

=> "When objects A and B are brought together, they repel."

DEDUCTIONS: A and B do not attract which is because A and B POSSESS THE SAME SIGN.

=> "When objects B and C are brought together, they also repel."

DEDUCTION: A and C POSSESS THE SAME SIGN.

CONCLUSION: Thus, If A and B do not attract and B and C also repel, then, it is possible that A, B and C are of the same sign. The law in which this follows is known as the law of transitivity.
