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 the liquid is T and angle of contact 
, then rise of liquid between the plates due to capillary will be
A
B
. C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
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
… (i)
Weight of the liquid rises in between the plates
… (ii)
Equating Eqs. (i) and (ii), we get
