1.	Water rises in a capilaary tube to a height of 2.0cm. In another capilary tube of radius one third of the first, water remains at a partricular height inside it. Find the height of water in the second capillary.
Answer» SOLUTION :Given `h_(1)=2cm""r_(2)=(r_(1)/3)` since `h ALPHA 1/R ""h_(2)/h_(1)=r_(1)/r_(2)` i.e,` h_(2)=(r_(1)/r_(2))h_(1)=((3r_(2))/(r_(2))h_(1)=3 XX 2,""i.e, h_(2)=6cm.`
