Q2: A level was set up midway between two pegs (A) and (B), 100m apart. The staff readings on pegs (A) and (B) were 2.325m and 3.020m respectively. The level was then set up over peg (A); the staff readings on pegs (A) and (B) were 1.520m and 2.285m respectively. Find out the error in the line of collimation and correct staff reading on peg (B) from the second position of the instrument.
