water rises in a capillary tube to a height of 1 cm. In another capillary where the radius is one-third of it, how high will the water rise (in cm)?

Answer

3

Explanation

Water rise in cap i 11 a ry tube, `h = ( 2 T cos theta)/( rlg)`
Since `h prop (1)/(r),` when radius is reduced to r one-third, the height increases to three times.
