Two narrow tube of diameters and are joined together to form a Utube open at both ends. If U-tube contains water, the difference in water levels in the limbs is ( is the surface tension of water, angle of contact is zero and density of water is is the acceleration due to gravity)
Options:
Answer:
A
Solution:
Consider the situation below:
When angle of contact is zero degree, the radius of meniscus equals the radius of tube.
Excess pressure in the first tube
Excess pressure in the second tube,
Hence, the pressure difference in the two limbs of the tube is given by,
