Properties Of Solids And Liquids Question 162

Question: Two parallel glass plates are dipped partly in the liquid of density ’d’ keeping them vertical. If the distance between the plates is ‘x’, surface tension for liquids is T and angle of contact is $θ$ , then rise of liquid between the plates due to capillary will be[NCERT 1981]

Options:

A) $\frac{T \cos θ}{x d}$

B) $\frac{2 T \cos θ}{x d g}$

C) $\frac{2 T}{x d g \cos θ}$

D) $\frac{T \cos θ}{x d g}$

Show Answer

Answer:

Correct Answer: B

Solution:

Let the width of each plate is b and due to surface tension liquid will rise upto height h then upward force due to surface tension = $2 T b \cos θ$ -(i)

Weight of the liquid rises in between the plates = $V d g = (b x h) d g$ -(ii)

Equating (i) and (ii) we get , $2 T \cos θ = b x h d g$

$∴ h = \frac{2 T \cos θ}{x d g}$
