Q1.	Which of the following errors cannot be eliminated by taking both face observations ?
A.	error due to horizontal axis not being perpendicular to the vertical axis [Wrong Answer]
B.	index error i.e. error due to imperfect adjustment of the vertical circle vernier [Wrong Answer]
C.	error due to non-parallelism of the axis of telescope level and line of collimation [Wrong Answer]
D.	none of the above [Correct Answer]
View Answer 24 -3 Explanation:- Answer : D Discuss it below : Himanshu Gupta Said on 2019-06-25 02:04:37 all three options are synonyms of collimation error, which is eliminated by taking both face reading. Hence the answer is 'd'. i.e. 'None of these' !! OOPS Login [Click here] is required to post your answer/result Help other students, write article, leave your comments
