On a cold dry day a child takes two balloon and rub against his sweate...
because same charge is produced in both the balloons so they repel b. yes balloons stick because balloon may have opposite charge of wall so it sticks and positive charge attract negative one and negative attracts positive one
On a cold dry day a child takes two balloon and rub against his sweate...
Explanation:
Opposite Charges:
When the child rubs the balloons against his sweater, a process called "triboelectric charging" occurs. This process involves the transfer of electrons between two materials. In this case, the balloons and the sweater have different abilities to gain or lose electrons. The friction between the balloons and the sweater causes the transfer of electrons, resulting in the balloons becoming charged.
- When the two charged balloons are brought near each other, they repel each other. This can be explained by the principle that like charges repel. Since both balloons acquired the same type of charge (either positive or negative) during the rubbing process, they have the same charge and, therefore, repel each other.
Attracted to Opposite Charges:
- On the other hand, when one of the charged balloons is taken near the wall, it sticks to it. This can be explained by the principle that opposite charges attract. The wall, being a neutral object, has an equal number of positive and negative charges. When the charged balloon is brought close to the wall, it induces a separation of charges on the wall's surface. The opposite charges on the wall are attracted to the charged balloon, causing it to stick to the wall.
Static Electricity:
The phenomena observed in this scenario are related to static electricity. Static electricity occurs when there is an imbalance of electric charges on the surface of an object. This imbalance can be created through processes like friction, as demonstrated by the child rubbing the balloons against his sweater.
- When the balloons are charged, they create an electric field around them. This electric field interacts with other charged objects, causing attractions or repulsions depending on the charges involved.
Conclusion:
In summary, when the child rubs the balloons against his sweater, they become charged. The balloons repel each other because they have the same charge, and they stick to the wall because the opposite charges on the wall are attracted to the charged balloon. These phenomena can be explained by the principles of opposite charges attracting and like charges repelling, which are fundamental concepts in electricity.
