What is the least count of the vernier callipers ?




What is the least count of commonly available vernier ?




When the zero mark on the vernier scale lies towards the left side of the zero mark of the main scale, when the jaws are connect, then what will be the zero error ?




When the zero mark on the vernier scale lies towards the right side of the zero mark of the main scale, when the jaws are in contact, then what will be the zero error ?




If observed reading is OR, corrected reading is CR, zero error in ZE and zero correction in ZC, then what will be the possibility ?




When the jaws of a standard vernier are together, the 6th vernier scale division coincides withthe 6th main scale division, then what in the zero error ?




When the jaws of a standard vernier are together, the 6th main scale division coincides with the 7th vernier scale division, then what is the zero error ?




In an anusualvernier, 9 vernier scale divisions coincide with 8 main scale division, then what is the least count of the vernier ?




In an unsual vernier, 10 vernier scale divisions, coinside with 8 main scale divisions, thenwhat isthe least count of the vernier ?




N divisions on the main scale of a vernier callipers coincides with (N+1) divisions on the vernier scale. If each division on the mainscale is of a units, the least of count of instrument is




The edge of a cube is measured using a vernier caliper (9 divisions of the main scale is equal to 10 divisions of vernier scale and 1 main scale division is 1mm). The main scale division reading is 10 and 1 division of vernier scale was found to be coinciding with the mainscale. The mass of the cube is 2.736 g. What will be the density in $g/cm^3 $ upto correct significant figures ?




When the edge of the circular scale lies to the left of O mark on the main scale, when the stud and spindle touch each other, Then what will be the zero error ?




When the edge of the circular scale lies to the right of the O mark on the main scale, when the stud and the spindle touch each other,then what will be the zero error ?




When the screw and stud touch each other, the edges of a certain screw gauge is on left of the O mark on the main scale and the 96th division of the circular scale coincides with the circular line of graduation then what is the value of zero error ?




When the screw and stud touch each other, the edge of a certain screw gauge is to the right of the O mark on the main scale and 5th division of the circular scale coincides with the line of graduation, then what is the value of zero error ?
