If the surface tension of water is 0.06 ...

If the surface tension of water is `0.06 Nm^(-1)`, then the capillary rise in a tube of diameter 1 mm is (angle of contact = `0^@`) ………….. .

A

1.22 cm

B

2.44 cm

C

3.12 cm

D

3.86 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`h= (2Tcos theta)/(rpg) = (2xx 0.06 xx 1)/(0.5xx10^(-3) xx 10^3 xx 9.8) = 2.44` cm
