Two thermocol balls held close to each other move away from each other. When they are released, name the force which might be responsible for this phenomenon. Explain.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Scenario**: We have two thermocol balls that are held close to each other and then released. Upon release, they move away from each other.

2. **Identifying the Type of Charge**: When two objects, like our thermocol balls, are brought close together, they can acquire electric charges. If both balls have the same type of charge (either both positive or both negative), they will experience a force that causes them to repel each other.

3. **Understanding the Force at Play**: The force that causes the two balls to move away from each other is known as the electrostatic force. This force arises due to the interaction between charged objects.
