# Find the Height to Which the Same Water Will Rise in Another Glass Capillary Having Half Area of Cross Section. - Physics

#### Question

Water rises to a height 3.2 cm in a glass capillary tube. Find the height to which the same water will rise in another glass capillary having half area of cross section.

#### Solution

h_1 = 3.2cm, A_2 = (A_1)/2

As, h  α  1/r

therefore h_1r_1 = h_2r_2

pir_2^2 = (pir_1^2)/2

=> r_2 = (r_1)/sqrt2

therefore h_2 = (3.2 xx r_1)/(r_1//sqrt2) = 3.2 xx sqrt2

Hence, h_2 = 4.525 cm

Is there an error in this question or solution?
