Object C: Attracts B

Object D: Repels C
Object E: Attracts D, Repels F
Object F: Attracts A

Michael is investigating the charge of several objects and records his findings in the data table. Michael knows that Object A is negatively charged.

What can Michael conclude about the charge of Objects C, D, E, and F?

A: C, D, E and F are negative.
B: C, D, E, and F are positive.
C: E and F are positive; C and D are negative.

D: C is positive and D, E, and F are negative.

that isn't an answer choice

My apologies. Based on the given information, Michael can conclude that Object C is positive and Objects D, E, and F are negative in charge.

The answer choices are:

A: C, D, E and F are negative.
B: C, D, E, and F are positive.
C: E and F are positive; C and D are negative.

Choose one.

The correct answer is C: E and F are positive; C and D are negative.

Based on the information provided, Michael can conclude that:

C: E and F are positive; C and D are negative.

Object C attracts Object B, which means they have opposite charges. Object D repels Object C, so they have the same charge but reversed. Object E attracts Object D, indicating that they have opposite charges. Lastly, Object F attracts Object A, which means they again have opposite charges.

Therefore, we can conclude that Objects E and F are positive, while Objects C and D are negative.

To determine the charge of Objects C, D, E, and F, we can analyze the given information about their interactions.

1. Object C attracts Object B: The fact that Object C attracts Object B tells us that Object C must have an opposite charge to Object B. Since Object B is not mentioned to have a charge, we cannot determine the charge of Object C solely based on this information.

2. Object D repels Object C: The fact that Object D repels Object C tells us that Object D must have the same charge as Object C. However, since we don't know the charge of Object C, we also cannot determine the charge of Object D from this information alone.

3. Object E attracts Object D and repels Object F: The fact that Object E attracts Object D tells us that Object E must have an opposite charge to Object D. Similarly, the fact that Object E repels Object F tells us that Object E must have the same charge as Object F.

4. Object F attracts Object A: The fact that Object F attracts Object A tells us that Object F must have an opposite charge to Object A, which is stated to be negatively charged.

Based on this information, we can conclude that:

- Object C and Object D have the same charge since they repel each other.
- Object E and Object F have the same charge since they attract each other.
- Object F has an opposite charge to Object A, which is negative.

Therefore, we can conclude that:
C: E and F are positive; C and D are negative.
