    `+0.3 cm`
    B
    `+0.03`
    C
    `+0.12 mm`

    If p divisions on the vernier scale of vernier calipers correspond to q main scale divisions (p > q), derive an expression for the least count of the instrument in terms of p and q. If 1 M.S.D. = k mm, express the least count in cm.

    The least count of a vernier calipers 'X' is 0.01 cm. If the number of divisions on the vernier scale of another vernier calipers 'y' is double of that in 'X' , then the least count of 'Y' is _______ mm. (in both instruments 1 M.S.D. = 1mm)

    The internal jaws of a vernier calipers were held tightly inside a hollow tube when the zero of the vernier scale showed a reading of 1.9 cm and the 18th division on the vernier scale was coinciding with a division on the main scale. The thickness of the wall of the tube is 1 mm. If 1 M.S.D. = 1 mm and the number of divisions on the vernier scale is 20, find the outside diameter of the hallow tube.
