Identify the incorrect statements for electric charge q :-

Options

A. Quantised
B. Conserved
C. Additive
D. Non - transferable

Answer

To identify the incorrect statements regarding electric charge \( q \), let's analyze each option step by step:

### Step 1: Understanding Charge Quantization
**Statement:** Charge is quantized.
**Explanation:** Electric charge is quantized, meaning it exists in discrete amounts. The charge \( q \) can be expressed as \( q = n \cdot e \), where \( n \) is an integer (0, 1, 2, ...) and \( e \) is the elementary charge (approximately \( 1.6 \times 10^{-19} \) coulombs). This means that charge can only take on values that are integer multiples of \( e \).
**Conclusion:** This statement is **correct**.

### Step 2: Understanding Charge Conservation
**Statement:** Charge is conserved.
**Explanation:** According to the law of conservation of charge, the total electric charge in an isolated system remains constant. Charge cannot be created or destroyed; it can only be transferred from one body to another.
**Conclusion:** This statement is **correct**.

### Step 3: Understanding Charge Additivity
**Statement:** Charge is additive.
**Explanation:** Electric charges can be added or subtracted. For example, if one body has charge \( Q \) and another body has charge \( q \), the total charge when they interact is \( Q + q \). This property allows us to calculate the net charge in a system.
**Conclusion:** This statement is **correct**.

### Step 4: Understanding Charge Transferability
**Statement:** Charge is non-transferable.
**Explanation:** This statement is incorrect. Charge can be transferred from one object to another. For example, when two objects come into contact, electrons can move from one to the other, resulting in a transfer of charge.
**Conclusion:** This statement is **incorrect**.

### Final Conclusion
The incorrect statement regarding electric charge \( q \) is the one that claims charge is non-transferable.

### Summary of Steps
1. **Quantization of Charge:** Charge exists in discrete amounts (correct).
2. **Conservation of Charge:** Charge cannot be created or destroyed (correct).
3. **Additivity of Charge:** Charges can be added or subtracted (correct).
4. **Transferability of Charge:** Charge can be transferred between bodies (incorrect).
