A glass rod of diameter d 1 = 1.5 mm is inserted symmetrically into a glass capillary with inside diameter d 2 = 2.0 mm. Then the whole arrangement is vertically oriented and brought in contact with the surface water To what height (cm) will the liquid rise in the capillary. Surface tension of water = 73 × 10 -3 N/m, Angle of contact = 0º. (use g = 9.8 m/s 2 )

Sol. Now there will be two meniscuses. (meniscuses)
Net upward surface tension force is balanced by the weight of the column.
⇒ T × 2 π 
+ T × 2 π 
= π × 
we get h = 
= 6 cm.
