In a -shaped tube the radius of one limb is and that of other limb is . A liquid of surface tension , density and angle of contact zero is taken in the tube. The difference in the heights of the levels of the liquid in the two limbs is
(Acceleration due to gravity )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Height of capillary rise in tube is given by h=2Tcosθrρg, here, Tis surface tension, θ is angle of contact, r is radius of capillary tube and ρ is density of liquid. Here, h1=2Tr1ρg and h2=2Tr2ρg Now, the difference in liquid evels in the two limbs…
