The correct Answer is:
To solve the problem, we need to analyze the situation step by step. ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have a metal object A that is connected to the earth via a connecting wire. This means that object A can exchange charges with the earth. 2. **Introducing Object B**: - A positively charged object B is brought closer to object A without touching it. The presence of the positively charged object B will influence the charge distribution on object A. 3. **Induction Process**: - When the positively charged object B is brought near A, it induces a charge separation in object A. The side of object A that is closer to B will experience a deficiency of electrons (becoming positively charged), while the side farther from B will have an excess of electrons (becoming negatively charged). 4. **Connection to Earth**: - Since object A is connected to the earth, electrons from the earth can flow into object A. This is crucial because the positive charge induced on the side of A facing B will attract electrons from the earth. 5. **Flow of Electrons**: - Electrons will flow from the earth to object A to neutralize the positive charge that has been induced by the presence of object B. This flow of electrons will continue until the positive charge on A is neutralized. 6. **Conclusion**: - Therefore, the correct statement is that electrons will flow from the earth to object A. ### Final Answer: Electrons will flow from Earth to A.
