139964 Using screw gauge of pitch \(0.1 \mathrm{~cm}\) and 50 divisions on its circular scale, the thickness of an object is measured. It should correctly be recorded as

139965 A screw gauge has 50 divisions on its circular scale. The circular scale is 4 units ahead of the pitch scale marking, prior to use. Upon one complete rotation of the circular scale, a displacement of \(0.5 \mathrm{~mm}\) is noticed on the pitch scale. The nature of zero error involved and the least count of the screw gauge, are respectively

139966 A student measuring the diameter of a pencil of circular cross-section with the help of a vernier scale records the following four readings; 5.50 \(\mathrm{mm}, 5.55 \mathrm{~mm}, 5.45 \mathrm{~mm}\) and \(5.65 \mathrm{~mm}\). The average of these four readings is \(5.5375 \mathrm{~mm}\) and the standard deviation of the data is \(0.07395 \mathrm{~mm}\). The average diameter of the pencil should be therefore recorded as

139967 If the screw on a screw gauge is given six rotations, it moves by \(3 \mathrm{~mm}\) on the main scale. If there are 50 divisions on the circular scale, the least count of the screw gauge is
