A negative declination shows the magnetic, meridian to the, (a) eastern side of the true meridian, (b) western side of the true meridian, (c) southern side of the true meridian, (d) none of these, , 41. Ifthe magnetic bearing of sun at noon at a place in, southern hemisphere is 150° the magnetic, declination at that place is, (a) 30°E (6) 30°W, (c) 20°E (d) 20°W, , 42. Isogonic lines are, (a) lines passing through points having same, declination at a given point, (b) line passing through point of zero declination, (c) line passing through point having same dip, (d) line passing through point having zero dip., , 43. Angle of dip at pole is, (a) 0° (b) 90°, (c) 45° (d) 30°, , 44, The true bearing of a line can be calculated as, , (a) True bearing, , = magnetic bearing + magnetic declination, (6) True bearing, , = magnetic bearing — magnetic declination, (c) True bearing, , = magnetic declination— magnetic bearing, (d) None of these, where the declination is to the east, , 45. The value of magnetic declination if the magnetic, bearing of sun at noon is 350°, (a) 10°E (6) 10°W, (c) 80°E (d) 80°W, , 46. In Bowditch rule of traverse adjustment it is, assumed that the errors in the linear, measurements are, (a) proportional to Me, (6) proportional to L, , (ec) inversely proportional to VE, (d) inversely proportional to L, , 47. Quadrantal system confines the user to measure, the bearing from, (a) the north point clockwise, (6) the north point or south point whichever, is nearer, (c) the north point anti-clockwise, (d) none of these, , 48. A bearing noted 45° NE represents, (a) Quadrantal system, , (6) Whole circle system, , (ce) Reduced bearing system, , (d) None of these, , , , 49., , 50., , 51., , 52., , 54., , 55., , 56., , 57., , 58., , i ing 338°42’ converted into, The whole circle bear! , is given, quadrant form ( ;, W 21 18’N (d) none of these, (c) ., , Local attraction in a compass surveying may be, , due to ‘, j tin compass, , faulty adjustmen”, , . ae to presence of magnetic materials, , tism in the needle, , loss of magne, Oo friction of the needle at the point., , The dip of the needle, (a) is constant, (b) varies from p, , equator and max, (c) is zero at the equa, (d) none of these, , Jace to place and is zero at the, imum at the poles, tor and poles, , The angle which the true meridian makes with, , magnetic meridian is called, (a) magnetic dclination or declination, (6) true declination, , (c) dip, , (d) azimuth, , Magnetic declination, , (a) remains same at different places, (6) varies from place to place, , (c) does not vary with temperature, (d) none of these, , If the needle of the compass is sluggish, the type, of error will be, , (a) instrumental error, , (6) personal error, , (c) natural error, , (d) none of these, , Difference between the most probable value of a, quantity and the observed value is, (a) conditional error (6) true error, , (c) resisdual error (d) safe error, , Temporary adjustment of a prismatic compass 1s, (@) centring, , (6) adjustment of levels, , (c) adjustment of needle, , (d) adjustment of van., , True meridi, a es are generally preferred over, enevic meridians because, , ®) ne converge to a point, , 1ese change due t oe, (c) these remain ee in time, (d) none of these, , Spire test is used fo, (a) line of sight, , (6) horizontal axis, (c) vertical axis, (d) adjustment of altitude bubble, , r adjustment of
