Question

Water rises to a height of 16.3 cm in a capillary of height 18 cm above the water level. If the tube is cut at a height of 12 cm in the capillary tube, (A) water will come as a fountain from the capillary tube (B) water will stay at a height of 12 cm in the capillary tube (C) the height of water in the capillary tube will be 10.3 cm (D) water height flow down the sides of the capillary tube

There will be no over flowing of liquid in a tube of insufficient height but there will be adjustment of the radius of curvature of meniscus so that h R=a finite constant.

Q. Water rises to a height of $16.3 c m$ in a capillary of height $18 c m$ above the water level. If the tube is cut at a height of $12 c m$ in the capillary tube,

water will come as a fountain from the capillary tube

water will stay at a height of 12 cm in the capillary tube

the height of water in the capillary tube will be 10.3 cm

water height flow down the sides of the capillary tube

There will be no over flowing of liquid in a tube of insufficient height but there will be adjustment of the radius of curvature of meniscus so that $h R = a$ finite constant.
