Electric charge of any system is

Options

A. Zero or neutral
B. Half integral multiple of the least amount of charge
C. Integral multiple of least amount of charge
D. Twice the least amount of charge

Explanation

### Step-by-Step Solution:

1. **Understanding Electric Charge**:
- Electric charge is a fundamental property of matter, present in particles such as protons and electrons. It is responsible for electromagnetic interactions.

2. **Quantization of Charge**:
- Electric charge is quantized, meaning it exists in discrete amounts rather than a continuous range. The smallest unit of charge is denoted as \( e \).

3. **Value of Elementary Charge**:
- The value of the elementary charge \( e \) is approximately \( 1.6 \times 10^{-19} \) coulombs. This is the charge of a single proton or the negative charge of a single electron.

4. **Integral Multiples**:
- The total electric charge \( Q \) of any system can be expressed as an integral multiple of the elementary charge. This can be mathematically represented as:
\[ Q = n \cdot e \]
where \( n \) is an integer (which can be positive or negative) and \( e \) is the elementary charge.

5. **Conclusion**:
- Therefore, the electric charge of any system is an integral multiple of the least amount of charge, which is the elementary charge \( e \). Thus, the correct answer is that the electric charge of any system is integral.

### Final Answer:
The electric charge of any system is an integral multiple of the least amount of charge.
