Lines joining points of equal magnetic declination are called:
सही उत्तर: घ) Isogonic lines
Isogonic lines join places with the same magnetic declination.

-
The magnetic bearing of a line is 120° and the magnetic declination is 5° West. The true bearing of the line is:
सही उत्तर: क) 115°
True bearing = magnetic bearing − west declination = 120° − 5° = 115°.

-
The fore bearing of a line is 45°. Its back bearing is:
सही उत्तर: ख) 225°
Back bearing = fore bearing ± 180° = 45° + 180° = 225°.

-
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.
