Question

Two inflated balloons are rubbed with a woolen cloth and are brought close to each other. If they repel each other it means that the nature of the charge on one balloon is different from the other.

• A. True
• B. False

Answer 1

The correct option is B False

Charging by rubbing:

1. When two objects are rubbed by each other, the free charges from one object move to the other, creating a charged object. This is also known as static electricity.
2. Static electricity refers to an imbalance between the electric charges in a body, specifically the imbalance between the negative and the positive charges on a body. The imbalance in the charge is introduced by physical means. One of the most common causes of static electricity is the contact between solid objects.

Attraction and repulsion between charged and neutral objects:

1. When a charged object is brought closer to a neutral object, attraction can be seen between the two objects.
2. If one object is neutral, and the other one is charged, the two objects will attract each other. In this case, the charged object may be positive or may be negative.
3. Again, two charged objects having opposite charges will also attract each other.
4. If the charges are the same, only then the two objects will repel each other.

Hence, the given statement is false.
