Q275.
Pick up the correct statement from the following :

a.

to locate a gross error in bearing that may exist in controlled theodolite traverse, we may plot the traverse from each end. The traverse station having the same coordinates by each route is the one where the error lies

b.

to locate a gross error in bearing, in a controlled traverse, we plot the traverse and the station through which perpendicular to sector of the closing line passes is the station at which the error was made

c.

to locate a gross error due to taping in a controlled traverse, we plot the traverse to a convenient scale. The bearing of the closing error will be approximately the same as that of the leg in which the gross error consists

d.

all the above.

Discuss
Answer: (d).all the above.
Q276.
Pick up the correct statement from the following :

a.

The horizontal angle between magnetic meridian and true meridian at a place is called magnetic declination or variance of the compass

b.

the imaginary lines which pass through points at which the magnetic declinations are equal at a given time are called isogonic lines

c.

the isogonic lines through places at which the declination is zero are termed agonic lines

d.

all the above.

Discuss
Answer: (d).all the above.
