For the following statement. write 'T' for True and 'F' for False.
The mass of an electron is about `(1)/(2000)` times that of proton.

Answer

To determine whether the statement "The mass of an electron is about (1/2000) times that of a proton" is true or false, we can follow these steps:

### Step 1: Understand the Mass of an Electron and Proton
- The mass of an electron is approximately \(9.10938 \times 10^{-31}\) kg.
- The mass of a proton is approximately \(1.6726 \times 10^{-27}\) kg.

### Step 2: Calculate the Ratio of the Masses
- To find out how many times the mass of an electron is compared to the mass of a proton, we can set up the ratio:

\[ \text{Ratio} = \frac{\text{Mass of Electron}}{\text{Mass of Proton}} = \frac{9.10938 \times 10^{-31}}{1.6726 \times 10^{-27}} \]

### Step 3: Perform the Calculation
- Performing the division:

\[ \text{Ratio} \approx \frac{9.10938}{1.6726} \times 10^{-31 + 27} = \frac{9.10938}{1.6726} \times 10^{-4} \]

- This gives us approximately:

\[ \text{Ratio} \approx 0.00544 \text{ (or about } \frac{1}{1836} \text{)} \]

### Step 4: Compare with the Given Statement
- The statement claims that the mass of the electron is about \( \frac{1}{2000} \) times that of the proton.
- Since \( \frac{1}{1836} \) is not equal to \( \frac{1}{2000} \), the statement is not accurate.

### Conclusion
- Therefore, the statement "The mass of an electron is about (1/2000) times that of a proton" is **False (F)**.
