139960 A student measured the diameter of a small steel ball using a screw gauge of least count \(0.001 \mathrm{~cm}\). The main scale reading is \(5 \mathrm{~mm}\) and zero division of the circular scale coincides with 25 division above the reference level. If the screw gauge has a zero error of \(0.004 \mathrm{~cm}\). the correct diameter of the ball is
139961 A screw gauge gives the following readings when used to measure the diameter of a wire Main scale reading : \(0 \mathrm{~mm}\) Circular scale reading: \(\mathbf{5 2}\) divisions Given that, \(1 \mathrm{~mm}\) on main scale corresponds to 100 divisions on the circular scale. The diameter of the wire from the above data is
139962 In an experiment the angles are required to be measured using an instrument in which 29 divisions of the main scale exactly coincide with the 30 divisions of the vernier scale. If the smallest division of the main scale is half a degree \(\left(=0.5^{\circ}\right)\), then the least count of the instrument is
139963 The least count of the main scale of a vernier callipers is \(1 \mathrm{~mm}\). Its Vernier scale is divided into \(10^{\text {th }}\) division and coincide with \(9^{\text {th }}\) division of the main scale. When jaws are touching each other, the \(7^{\text {th }}\) division of vernier scale coincides with a division of main scale and the zero of vernier scale is lying right side of the zero of main scale. When this vernier is used to measure length of a cylinder the zero of the vernier scale lies between \(3.1 \mathrm{~cm}\) and \(3.2 \mathrm{~cm}\) and \(4^{\text {th }}\) VSD coincides with a main scale division. The length of the cylinder is (VSD is vernier scale division)
