Question

SECTION - A NCERT Based MCQs The source of instrumental error is [NCERT Pg. 23] (1) Improper designing or calibration (2) Zero error (3) External conditions (4) Both (1) & (2) connected in​

Answer 1

Answer:

Option (4) is correct Both 1 & 2

Explanation:

The systemic errors include instrumental error.

• Instrumental errors result from inaccurate measuring equipment calibration, a 0 inaccuracy in the a flawed design, an instrument, etc.

Using a thermometer as an example the gradations of a temperature possibly not be accurate enough

When using vernier callipers, for example, the zero mark of the vernier scale may not be calibrated (it may read 104 °C at the boiling point of water at STP when it should read 100 °C);

correspond to the primary's zero marks scale. . Due to the possibility of both flawed design and flawed implementation causing an error, the calibration of the measurement device,

Option (4) is correct Both 1 & 2

Answer 2

Answer:

Option (4)  Both 1 & 2

Explanation:

Instrumental errors are caused by poor measurement equipment calibration, an instrument's lack of accuracy, a flawed design, etc.

The temperature readings on a thermometer, for instance, may not be accurate enough.

For instance, when using vernier callipers, it is possible that the zero mark of the vernier scale is improperly calibrated (reading 104 °C at the boiling point of water at STP when it should read 100 °C);

conform to the primary's grading system of zero marks. The calibration of the measurement equipment, because both faulty execution and flawed design could result in an error,

Choice (4) is accurate. Both 1 & 2
