QUESTION: 1

In the prismatic compass 

Solution:
QUESTION: 2

Local attraction in compass surveying may exist due to

Solution:

Local attraction is a term used to denote any influence, which prevents the needle from pointing to the magnetic north in a given locality. Difference of fore bearing and back bearing = 0 ⇒ No local attraction.

QUESTION: 3

The horizontal angle between the true meridian and magnetic meridian at a place is called

Solution:
QUESTION: 4

A negative declination shows that the magnetic meridian is to the

Solution:
QUESTION: 5

If the lower clamp screw is tightened and upper clamp screw is loosened, the theodolite may be rotated

Solution:
QUESTION: 6

The error due to eccentricity of inner and outer axes can be eliminated by 

Solution:

Error due to eccentricity of inner and outer axes means that the centre of graduated horizontal circle does not coincide with the centre of vernier plate.

QUESTION: 7

While measuring horizontal angles by the method of repetition with a theodolite, readings are taken on both the verniers. Which one of the following errors will be eliminated by reading both the verniers?

Solution:
QUESTION: 8

If the quadrantal bearing of a line is N25°W, then the whole circle bearing of the line is

Solution:
QUESTION: 9

The following bearings were observed while traversing with a compass:

Which stations were affected by local attraction?

Solution:

As the difference between F.B and B.B of line AB is exactly 180°, stations A and B are free from local attraction which is not the case with line CD.
Hence stations C and D are affected by local attraction.

QUESTION: 10

The coordinates of two end-points A and B of a traverse line AB are 
XA = 1000.00 m, YA = 10000.00 m
XB = 2000.00 m, YB = 1000.00 m 

The bearing of the line AB will be
