An electric charge does not have which of the following properties?

Options

A. Total charge conservation
B. Quantisation of charge
C. Two types of charge
D. Circular line of force

Answer

To determine which property an electric charge does not have, we need to analyze the properties of electric charges. Here’s a step-by-step solution:

### Step 1: Understand the Properties of Electric Charge
Electric charges have several fundamental properties. Some of the key properties include:
1. **Conservation of Charge**: The total electric charge in an isolated system remains constant.
2. **Quantization of Charge**: Electric charge exists in discrete amounts, typically as integer multiples of the elementary charge (e).
3. **Types of Charge**: There are two types of electric charge: positive and negative.
4. **Electric Field Lines**: The electric field lines produced by a charge are straight lines, not circular.

### Step 2: Analyze Each Property
- **Total Charge Conservation**: This property states that charge cannot be created or destroyed. It is a fundamental principle in physics and is always true for electric charges.

- **Quantization of Charge**: This property indicates that charges are quantized and can only exist in integer multiples of the elementary charge (e). This is also a true property of electric charges.

- **Types of Charge**: Electric charges can be positive or negative. This is a fundamental characteristic of electric charge and is true.

- **Electric Field Lines**: The electric field lines produced by a point charge are straight lines radiating outward (for positive charge) or inward (for negative charge). They do not form circular paths.

### Step 3: Identify the Incorrect Property
From the analysis:
- Total charge conservation, quantization of charge, and types of charge are all valid properties of electric charge.
- The property that states that electric field lines are circular is incorrect. Electric field lines are straight, not circular.

### Conclusion
The property that an electric charge does not have is **circular lines of force**.
