Two capillary tubes of different diameters are dipped in water.The rise of water is

A

The same in both tubes

B

Greater in the tube of larger diameter

C

Greater in the tube of smaller diameter

D

Independent of the diameter of the tube

Text Solution

Verified by Experts

The correct Answer is:
C
The rise of water in a capillary tube is
`h(2Tcostheta)/(rrhog)`
Where the symbols have their usual meaning `hprop(1)/(R )`
Hence,the rise of water is greater for the tube of smaller diameter.

The lower end of a capillary tube of diameter 2.00mm is dipped 8.00cm below the surface of water in a beaker. What is the pressure required in the tube in order to blow a hemispherical bubble at its end in water? The surface tension of water at temperature of the experiments is 7.30 times 10^2 Nm^-1 .1 atmospheric pressure =1.01 times 10^5 Pa density of water =1000 kg//m^3,g=9.80 ms^-2 . Also calculate the excess pressure.

What is a capillary tube?

When we press the bulb of a dropper with its nozzle kept in water , air in the dropper seems to escape in the form of bubbles. Once we release the pressure on the bulb , water gets filled in the dropper. The rise of water in the dropper is due to
