The line of collimation of a level is the line joining:
सही उत्तर: ग) The intersection of the cross hairs and the optical centre of the objective
The line of collimation (line of sight) passes through the cross-hair intersection and the optical centre of the objective.

A traverse line 200 m long has a reduced bearing N 30° E. Its departure is:
सही उत्तर: घ) +100.0 m
Departure = L sin θ = 200 × sin 30° = +100.0 m (east is positive).

The arithmetic check in the rise and fall method of levelling is:
सही उत्तर: ख) ΣBS − ΣFS = ΣRise − ΣFall = Last RL − First RL
In the rise and fall method all three differences must agree; this checks every reduced level including intermediate ones.

In the rise and fall method, if the staff reading at the preceding point is 1.800 m and at the next point is 1.200 m, there is a:
सही उत्तर: क) Rise of 0.600 m
A smaller reading means the point is higher: rise = 1.800 − 1.200 = 0.600 m.

A traverse line with reduced bearing S 30° W has latitude and departure with signs:
सही उत्तर: घ) Latitude negative, departure negative
South latitudes are negative and west departures are negative.

-
In the height of instrument (collimation) method, the reduced level of a point is obtained as:
सही उत्तर: घ) Height of instrument minus the staff reading
HI = RL of BM + BS; RL of any point = HI − staff reading at that point.

-
Coordinates of traverse stations referred to a common origin are called:
सही उत्तर: ख) Independent coordinates
Independent (total) coordinates are referred to a common origin; consecutive coordinates are latitude and departure of each line.

-
Deflection angle traversing is particularly suitable for:
सही उत्तर: घ) Open traverses such as roads, canals and railways
Long, gently curving routes like roads and canals are conveniently surveyed by deflection angles in an open traverse.

-
The last staff reading taken before shifting the level is called:
सही उत्तर: क) Fore sight
The fore sight is the last reading at a set-up, after which the instrument is moved.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The first staff reading taken on a point of known elevation after setting up the level is called:
सही उत्तर: घ) Back sight
A back sight is the first reading after setting up, taken on a point of known RL such as a benchmark.
