Water rises in a capillary tube to a height 2.0 cm. In an another capillary tube whose radius is one third of it, how much the water will rise ? If the first capillary tube is inclined at an angle of `60^@` with the vertical then what will be the position of water in the tube.

A

`2.0cm`

B

`4.0cm`

C

`(4)/sqrt(3)cm`

D

`2sqrt(2)cm`

Text Solution

Verified by Experts

The correct Answer is:
B
The height upto which water will rise `l=(h)/(cos alpha) = (2cm)/(cos 60) = 4cm`. `[h = "vertical height", alpha = "angle with vertical"]`
