Q2. The focal length of the object glass of a tacheometer is 200 mm, the distance
between the vertical axis of the tacheometer and the optical centre of the object
glass is 100 mm and the spacing between the upper and lower line of the diagram
axis is 4 mm. With the line of collimation perfectly horizontal, the staff intercepts
