Water rises to a height of 20 ~mm in a capillary tube of cross-sectional area A . If the area of cross-section of the tube is made ( A 4 ) , then water will rise to a height of

Options

  1. A2 cm
  2. B6 cm
  3. C4 cm
  4. D3 cm

Correct answer

C. 4 cm

Step-by-step solution

Capillary rise is given by, aligned & h= 2 T r g & h 1 r 1 A aligned If A become one-fourth, h becomes twice. h^ =40 ~mm =4 ~cm
