Explanation:
It is known that like charges tend to repel each other whereas unlike charges tend to attract each other. For example, when a positive charge comes closer to another positive charge then they will repel each other.
But when a negative charge is brought closer to a positive charge then they tend to attract each other.
Hence, to determine the charges present on the two objects we can perform additional experiments.
As it is given that when objects A and B are brought together, they repel. And, when objects B and C are brought together, they also repel. This means that A and C will also repel each other due to the presence of same charge.
This also means that all three objects possess charges of the same sign.
Therefore, we can conclude that the true statements are as follows.
- additional experiments must be performed to determine the signs of the charges.
- objects A and C possess charges of the same sign.
- all three objects possess charges of the same sign.
Objects A and B repel each other and objects B and C also repel each other. We can affirm that:
- a) additional experiments must be performed to determine the signs of the charges.
- b) objects A and C possess charges of the same sign.
- e) all three objects possess charges of the same sign.
What is Coulomb's law?
Coulomb's law is a law stating that like charges repel and opposite charges attract, with a force proportional to the product of the charges and inversely proportional to the square of the distance between them.
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 the charges. True. There is not enough information to determine the signs of the charges.
- b) objects A and C possess charges of the same sign. True. They must have the same sign since both of them repel B.
- c) one object is neutral. False. Neutral objects don't experience attraction or repulsion.
- d) objects A and C possess charges of the opposite sign. False. They must have the same sign since both of them repel B.
- e) all three objects possess charges of the same sign. True. They must be all positive or all negative.
Objects A and B repel each other and objects B and C also repel each other. We can affirm that:
- a) additional experiments must be performed to determine the signs of the charges.
- b) objects A and C possess charges of the same sign.
- e) all three objects possess charges of the same sign.
