    The vernier scale used for measurement has a positive zero error of 0.2 mm0.2\text{ }mm. If while taking a measurement it was noted that ' 0 ' on the vernier scale lies between 8.5 cm8.5\text{ }cm and 8.6 cm8.6\text{ }cm, vernier coincidence is 6 , then the correct value of measurement is ____ cm\_\_\_\_\ cm. (least count =0.01 cm= 0.01\text{ }cm )

    The diameter of a spherical bob is measured using a vernier callipers. 9 divisions of the main scale, in the vernier callipers, are equal to 10 divisions of vernier scale. One main scale division is 1 mm1\text{ }mm. The main scale reading is 10 mm10\text{ }mm and 8th 8^{\text{th~}} division of vernier scale was found to coincide exactly with one of the main scale division. If the given vernier callipers has positive zero error of 0.04 cm0.04\text{ }cm, then the radius of the bob is ____×10−2 cm\_\_\_\_\times10^{- 2}\text{ }cm.

    The vernier constant of Vernier callipers is 0.1 mm0.1\text{ }mm and it has zero error of (−0.05)cm( - 0.05)cm. While measuring diameter of a sphere, the main scale reading is 1.7 cm1.7\text{ }cm and coinciding vernier division is 5. The corrected diameter will be ____×10−2 cm\_\_\_\_\times10^{- 2}\text{ }cm.

    In a Vernier Calipers. 10 divisions of Vernier scale is equal to the 9 divisions of main scale. When both jaws of Vernier calipers touch each other, the zero of the Vernier scale is shifted to the left of zero of the main scale and 4th 4^{\text{th~}} Vernier scale division exactly coincides with the main scale reading. One main scale division is equal to 1 mm1\text{ }mm. While measuring diameter of a spherical body, the body is held between two jaws. It is now observed that zero of the Vernier scale lies between 30 and 31 divisions of main scale reading and 6th 6^{\text{th~}} Vernier scale division exactly. coincides with the main scale reading. The diameter of the spherical body will be:

    The one division of main scale of vernier callipers reads 1 mm1\text{ }mm and 10 divisions of Vernier scale is equal to the 9 divisions on main scale. When the two jaws of the instrument touch each other the zero of the Vernier lies to the right of zero of the main scale and its fourth division coincides with a main scale division. When a spherical bob is tightly placed between the two jaws, the zero of the Vernier scale lies in between 4.1 cm4.1\text{ }cm and 4.2 cm4.2\text{ }cm and 6th 6^{\text{th~}} Vernier division coincides with a main scale division. The diameter of the bob will be ____×10−2 cm\_\_\_\_\times10^{- 2}\text{ }cm.

    In an experiment with Vernier callipers of least count 0.1 mm0.1\text{ }mm, when two jaws are joined together the zero of Vernier scale lies right to the zero of the main scale and 6th 6^{\text{th~}} division of Vernier scale coincides with the main scale division. While measuring the diameter of a spherical bob, the zero of vernier scale lies in between 3.2 cm3.2\text{ }cm and 3.3 cm3.3\text{ }cm marks, and 4th 4^{\text{th~}} division of vernier scale coincides with the main scale division. The diameter of bob is measured as:

    When both jaws of Vernier calipers touch each other, zero mark of the vernier scale is right to zero mark of main scale, 4th 4^{\text{th~}} mark on Vernier scale coincides with certain mark on the main scale. While measuring the length of a cylinder, observer observes 15 divisions on main scale and 5th5^{\text{th}} division of Vernier scale coincides with a main scale division. Measured length of cylinder is ____\_\_\_\_ mm. (Least count of Vernier caliper =0.1 mm= 0.1\text{ }mm )
