The main scale of a vernier callipers is calibrated in mm and 19 divisions of main scale are equal in length to 20 divisions of vernier scale. In measuring the diameter of a cylinder by this instrument, the main scale reads 35 divisions and 4th division of vernier scale coinsides with a main scale division. Find:
(ii). Radius of cylinder(in cm)
    Correct answer is '1.76'. Can you explain this answer?

    The main scale of a vernier callipers is calibrated in mm and 19 divis...
    Main scale reading = 35 mm = 3.5 cm
    Diameter
    = Main scale reading + vernier coincidence × Least count
    = 3.5 + 4 × 0.005
    = 3.5 + 0.02
    = 3.52 cm
    Radius = Diameter/2 = 3.52/2 = 1.76 cm

    Given data:
    Main scale reading = 35 divisions
    Vernier scale reading = 4th division coincides with a main scale division
    1 main scale division = 1 mm
    19 main scale divisions = 20 vernier scale divisions

    Calculations:
    - Total reading = Main scale reading + (Vernier scale reading x least count)
    - Least count = 1 main scale division - 1 vernier scale division
    - Least count = 1 mm - (1 mm / 20) = 19/20 mm = 0.95 mm

    Using the formula:
    Total reading = 35 divisions + (4 x 0.95 mm)
    Total reading = 35 divisions + 3.8 mm
    Total reading = 38.8 mm

    Radius of the cylinder:
    - Diameter = 2 x radius
    - Diameter = Total reading
    - Radius = Total reading / 2

    Substitute the values:
    Radius = 38.8 mm / 2 = 19.4 mm = 1.94 cm
    Therefore, the radius of the cylinder is 1.94 cm.
