In a prismatic compass, the zero of the graduated ring is placed at the:
सही उत्तर: ग) South end
Since the reading is taken through the prism on the side opposite the object, zero is placed at the south end of the needle.

In a surveyor's compass, the letters E and W on the graduated ring are:
सही उत्तर: घ) Interchanged
In a surveyor's compass E and W are interchanged so that the bearing read directly gives the correct quadrant.

The Abney level is primarily used for:
सही उत्तर: क) Measuring slope angles
The Abney level (hand clinometer) measures vertical angles or slopes of the ground.

-
Which of the following errors in chaining is cumulative in nature?
सही उत्तर: ख) Error due to incorrect length of chain
A wrong chain length introduces an error of the same sign in every chain length, so it accumulates.

The normal tension in taping is the pull at which:
सही उत्तर: ग) The pull correction and sag correction cancel each other
Normal tension is the pull at which the positive pull correction equals the negative sag correction.

A 100 m steel tape (α = 12 × 10⁻⁶ /°C) is used at a temperature 20°C above its standard temperature. The temperature correction per tape length is:
सही उत्तर: घ) +0.024 m
Ct = αL(T − T₀) = 12×10⁻⁶ × 100 × 20 = +0.024 m (tape expands, so correction is additive).

The correction for sag in taping is always:
सही उत्तर: क) Negative (subtractive)
A sagging tape reads more than the true horizontal distance, so sag correction is always subtractive.

A 20 m chain was found to be 20.10 m long. A distance measured with it was recorded as 500 m. The true distance is:
सही उत्तर: ख) 502.5 m
True length = (L'/L) × measured = (20.10/20) × 500 = 502.5 m.

A line measured along a uniform slope is 30 m long and the difference in height between its ends is 1.5 m. The slope correction is approximately:
सही उत्तर: ग) 0.0375 m
Slope correction = h²/2L = 1.5²/(2×30) = 0.0375 m (subtractive).

In an optical square, the angle between the two mirrors is:
सही उत्तर: घ) 45°
Mirrors inclined at 45° deviate the line of sight by twice that angle, i.e. 90°.
