The measured value of physical quantity expressed to infinite number of decimals places is called

Options

A. practical value
B. ideal value
C. absolute value
D. real value

Answer

To solve the question, we need to identify the term that describes a measured value of a physical quantity expressed to an infinite number of decimal places.

### Step-by-Step Solution:

1. **Understanding Physical Quantities**:
- Physical quantities are measurable attributes such as mass, length, time, etc.
- They can be expressed in numerical form and can have varying degrees of precision.

2. **Concept of Measurement**:
- When we measure a physical quantity, we often encounter a degree of uncertainty due to limitations in measuring instruments and techniques.
- The precision of a measurement is typically limited by the smallest division of the measuring instrument.

3. **Infinite Decimal Places**:
- When a value is expressed to an infinite number of decimal places, it implies that there is no uncertainty in the measurement.
- This is a theoretical concept, as in practical scenarios, no measurement can be perfectly precise.

4. **Ideal Value**:
- A value expressed with infinite decimal places is referred to as an "ideal value."
- This term indicates that the measurement is considered perfect and accurate without any approximation.

5. **Conclusion**:
- Therefore, the measured value of a physical quantity expressed to an infinite number of decimal places is called an **"ideal value."**

### Final Answer:
The measured value of a physical quantity expressed to an infinite number of decimal places is called an **ideal value**.
