The lower end of a glass capillary tube is dipped in water. Water rises to a height of 9 cm. The tube is then broken at a height of 5 cm. the height of the water column and angle of contact will be

`5cm, cos^(-1)((5)/(9))`

`4cm, cos^(-1)((5)/(4))`

`5cm, cos^(-1)((9)/(5))`

`5cm, cos^(-1)((6)/(7))`
