Which of the following is a likely source of local attraction in compass surveying?
सही उत्तर: घ) Steel structures, iron pipes or electric cables nearby
Magnetic materials and currents (iron, steel, cables) near a station deflect the needle, causing local attraction.

Which of the following is a common use of contour maps?
सही उत्तर: क) Estimating the capacity of a reservoir
Contour maps help in reservoir capacity, catchment area, route location and intervisibility studies.

The true bearing of a line is 210° and magnetic declination is 4° West. The magnetic bearing is:
सही उत्तर: घ) 214°
True = Magnetic − West declination, so Magnetic = 210° + 4° = 214°.

On a contour map, a series of closed contours with values increasing towards the centre represents a:
सही उत्तर: घ) Hill
Closed contours with higher values inside indicate a hill; lower values inside indicate a depression.

The fore bearing of a line is S 40° E. Its back bearing is:
सही उत्तर: ग) N 40° W
In the quadrantal system, the back bearing has the same angle with opposite letters: N 40° W.

The horizontal distance between two consecutive contours on the ground is called the:
सही उत्तर: ख) Horizontal equivalent
Horizontal equivalent is the plan distance between successive contours; it varies with the steepness of the ground.

-
The reduced bearing of a line is N 35° W. Its whole circle bearing is:
सही उत्तर: घ) 325°
In the NW quadrant, WCB = 360° − 35° = 325°.

In levelling from a benchmark of RL 150.000 m, the sums of back sights and fore sights are 8.465 m and 10.215 m. The RL of the last point is:
सही उत्तर: क) 148.250 m
Last RL = First RL + ΣBS − ΣFS = 150.000 + 8.465 − 10.215 = 148.250 m.

Barometric levelling is based on the principle that atmospheric pressure:
सही उत्तर: ग) Decreases with increase in altitude
Since air pressure decreases with height, measuring pressure differences gives approximate elevation differences.

A levelling staff that is telescopic, with sections sliding into each other, is commonly known as:
सही उत्तर: ख) Sopwith staff
The Sopwith (telescopic) staff extends to about 4 m in sliding sections.
