The tracing paper method in plane tabling is used to solve the:
सही उत्तर: ग) Three-point problem
Rays to three known points are drawn on tracing paper, which is then moved until the rays pass through the plotted points, fixing the station.

A telescopic alidade is preferred over a plain alidade in plane tabling because it:
सही उत्तर: ख) Allows longer and inclined sights and tacheometric measurement of distances and elevations
The telescope gives a clear view over long distances and on slopes, and with stadia hairs it can also measure distances and heights.

Bessel's method in plane tabling is a graphical solution of the:
सही उत्तर: ख) Three-point problem
Bessel's method uses back-sighting along lines through the plotted points to locate the occupied station in the three-point problem.

In a tacheometric observation, the RL of the instrument axis is 100.500 m, the computed vertical component V is +5.200 m and the middle hair reading on the staff is 1.500 m. The RL of the staff station is:
सही उत्तर: ग) 104.200 m
RL = RL of axis + V − middle hair reading = 100.500 + 5.200 − 1.500 = 104.200 m.

A tacheometer with K = 100 and C = 0 is used with the line of sight inclined at 10° and a vertical staff. The staff intercept is 1.20 m. The horizontal distance is about:
सही उत्तर: क) 116.4 m
D = Ks cos²θ = 100 × 1.20 × cos²10° = 120 × 0.9698 ≈ 116.4 m.

In an external-focusing tacheometer without an anallactic lens, the additive constant C is equal to:
सही उत्तर: घ) f + d, the focal length plus the distance from the objective to the vertical axis
The additive constant equals the focal length plus the distance between the objective and the instrument's vertical axis; an anallactic lens makes it zero.

In stadia tacheometry, the multiplying constant K of a tacheometer is equal to:
सही उत्तर: ख) f/i, where f is the focal length and i is the stadia hair interval
Similar triangles give D = (f/i)s + (f + d), so K = f/i and the additive constant C = f + d.

A traverse line running due east has:
सही उत्तर: घ) Zero latitude and departure equal to its length
Latitude = L cos 90° = 0 and departure = L sin 90° = L.

The coordinate differences between two stations are ΔN = 30 m and ΔE = 40 m. The distance between them is:
सही उत्तर: क) 50 m
Distance = √(30² + 40²) = √2500 = 50 m.

The coordinates of B relative to A are ΔN = −100 m and ΔE = +100 m. The whole circle bearing of AB is:
सही उत्तर: क) 135°
Latitude negative and departure positive means the line lies in the SE quadrant; reduced bearing S 45° E corresponds to WCB 135°.
