Question
A level, when set up 25 m from peg A and 50 m
from peg B, reads 2.853 m on a staff held on A
and 4.462 m on a staff held on B, keeping the
bubble at its centre while reading. If the reduced
levels of A and B are 283.665 m and 285.295m
respectively, what is the collimation error per
100.0 m?
