Sonia was experimenting with electric charges. She tied two inflated balloons together, held them next to each other, and rubbed both with a piece of wool.
What did Sonia observe, and why?
Sonia observed that the two balloons repelled each other.
This occurred because when Sonia rubbed both balloons with the wool, the balloons gained a similar charge. Since like charges repel each other, the balloons exhibited repulsion when brought close to each other.
Sonia observed that the two balloons repelled each other. This is because both balloons acquired the same charge when she rubbed them with the piece of wool, and like charges repel each other.
What did you include in your response? Check all that apply.
The two balloons repelled each other.
Both balloons acquired the same charge.
Like charges repel each other.
In my response, I included the following statements:
- The two balloons repelled each other.
- Both balloons acquired the same charge.
- Like charges repel each other.
Describe what happens to the electric field lines when two objects with unlike charges are brought near each other.
When two objects with unlike charges are brought near each other, the electric field lines between them converge. The electric field lines originate from the positively charged object and terminate on the negatively charged object. This convergence of electric field lines indicates that there is an attractive force between the objects. The closer the objects are to each other, the stronger the electric field and the attraction between them.
When two objects with unlike charges are brought near each other, their electric field lines combine, showing that the objects attract each other.
