When a part of a straight capillary tube is placed vertically in a liquid, the liquid raises upto certain height 
. If the inner radius of the capillary tube, density of the liquid and surface tension of the liquid decrease by 
each, then the height of the liquid in the tube will change by 
.
Text Solution
Verified by ExpertsThe correct answer is:
A
Capillary height formula: 
When radius, density, and surface tension each decrease by 
New height: 
Percentage change: 
, which rounds to 
.
