The minimum real charge on any particle which can exist is

Options

A. `1.6xx10^(-19)` Coulomb
B. `1.6xx10^(-10)` Coulomb
C. `4.8xx10^(-10)` Coulomb
D. Zero

Explanation

To find the minimum real charge on any particle that can exist, we can follow these steps:

### Step 1: Understand the concept of elementary charge
The elementary charge (denoted as 'e') is the smallest unit of electric charge that is considered to be real and is carried by elementary particles such as electrons and protons.

### Step 2: Identify the value of the elementary charge
The value of the elementary charge is approximately:
\[ e = 1.6 \times 10^{-19} \text{ Coulombs} \]

### Step 3: State the minimum real charge
Since the elementary charge is the smallest charge that can exist in nature, we conclude that:
\[ \text{Minimum real charge} = 1.6 \times 10^{-19} \text{ Coulombs} \]

### Step 4: Conclusion
Thus, the minimum real charge on any particle which can exist is:
\[ \text{Minimum real charge} = 1.6 \times 10^{-19} \text{ C} \]
