The lower end of a capillary tube is dipped
into water and it is observed that the water
in capillary tube rises by 7.5 cm. Find the
radius of the capillary tube used, if surface
tension of water is 7.5 \(\times\) 10\(^{-2}\) Nm\(^{-1}\). Angle of contact between water and glass is 0\(\Upsilon\) and acceleration due to gravity is 10 ms\(^{-2}\).
