Which of the following error can be eliminated by taking the mean of ...
The errors that can be eliminated by changing face are as follows
View all questions of this test
1. Error due to the line of collimation not being perpendicular to the horizontal axis.
2. Error due to horizontal axis not being perpendicular to the vertical axis.
3. Error due to the line of collimation not being parallel to the axis of the altitude level.
∴ By taking the mean of both face observation, we eliminate error due to line of collimation not being perpendicular to the horizontal axis.

Error due to line of collimation not being perpendicular to the horizontal axis can be eliminated by taking the mean of both face observation. Let us understand this in detail:
Explanation:
- Line of collimation is an imaginary line that passes through the intersection of crosshairs of the telescope and the center of the object being sighted. It is essential that this line is perpendicular to the horizontal axis for accurate measurements.
- However, due to various factors such as human error, instrument error or environmental factors, this line may not always be perfectly perpendicular to the horizontal axis.
- This can lead to errors in measurements, which can be significant in certain applications such as surveying or construction.
- Taking the mean of both face observations can help eliminate this error. This involves taking two readings of the same object, one with the telescope facing in one direction and the other with the telescope facing in the opposite direction. The mean of the two readings can then be taken to eliminate any errors due to the line of collimation not being perpendicular to the horizontal axis.
- By taking the mean of both face observations, any errors due to misalignment of the line of collimation can be canceled out, resulting in a more accurate measurement.
Conclusion:
Therefore, option D is the correct answer to the question as error due to the line of collimation not being perpendicular to the horizontal axis can be eliminated by taking the mean of both face observation.
