    Select Question Language :


    The following observations were taken for determining surface tension T of water by capillary method:

    Diameter of capillary, D = 1.25 x 10–2 m; rise of water, h = 1.45 x 10–2 m

    Using g = 9.80 m/s2 and the simplified relation T =  x 103 N/m, the possible error in surface tension is closest to

    Options :-

    1. 2.4%
    2. 10%
    3. 0.15%
    4. 1.5%
