_______ is a temporary method of charging an object.

Options

A. charging by friction
B. charging by conduction
C. charging by induction
D. none of them

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question:**
The question asks for a temporary method of charging an object.

2. **Identifying Charging Methods:**
There are several methods of charging objects, including:
- Charging by friction
- Charging by conduction
- Charging by induction

3. **Defining Each Method:**
- **Charging by Friction:** This method involves rubbing two insulating materials together, which results in the transfer of electrons and creates a charge. This method is permanent.
- **Charging by Conduction:** This method involves direct contact between a charged object and a neutral object, allowing electrons to transfer. This method is also permanent.
- **Charging by Induction:** This method involves bringing a charged object close to a neutral object without direct contact. The neutral object becomes charged temporarily due to the influence of the nearby charged object.

4. **Identifying the Temporary Method:**
Among the methods listed, charging by induction is the only method that results in a temporary charge. The neutral object will lose its charge once the charged object is removed.

5. **Conclusion:**
Therefore, the answer to the question is: **Charging by Induction** is a temporary method of charging an object.
