Water rises to a height of 5 cm when a narrow glass tube is dipped vertically in it . If the tube is inclined at `60^(@)` to the vertical , then the rise of water in the capillary tube will be

5 cm

10 cm

`7.5` cm

`2.5` cm

Text Solution

Verified by Experts

The correct Answer is:

`h= rho cos theta`
` l = h/(coa theta )= 5/(cos 60 ) = 5/(1/2)= 5xx2 = 10 ` cm
