    -0.01 mm

    Explanation:

    We are given that

    The value of one division of vernier scale = 0.5 mm

    The value of one main scale division=0.49 mm

    We have to find the value of least count of the instrument in mm.

    We know that

    Leas count of vernier caliper=1 main scale division-1 vernier scale division

    Least count of vernier caliper=0.49-0.50=-0.01 mm

    Hence, the least count of the instrument=-0.01 mm

    Answer: - 0.01 mm
