JEE Main & Advanced Physics Fluid Mechanics, Surface Tension & Viscosity / द्रव यांत्रिकी, भूतल तनाव और चिपचिपापन Question Bank Capillarity

  • question_answer
    Water rises in a vertical capillary tube upto a height of 2.0 cm . If the tube is inclined at an angle of \[{{60}^{o}}\] with the vertical, then upto what length the water will rise in the tube    [UPSEAT 2002]

    A) 2.0 cm

    B)                      4.0 cm

    C)             \[\frac{4}{\sqrt{3}}cm\]

    D)                      \[2\sqrt{2\,}cm\]

    Correct Answer: B

    Solution :

                    \[l=\frac{h}{\cos \theta }=\frac{2}{\cos {{60}^{o}}}=4.0\ cm\]
