JEE Main 2014 — Mechanical Properties of Fluids Question with Solution

JEE Main 2014 (09 Apr Online)

Question

A capillary tube is immersed vertically in water and the height of the water column is x⁡ . When this arrangement is taken into a mine of depth d, the height of the water column is y⁡ . If R is the radius of earth, the ratio x⁡ y⁡  is :

Correct answer
D 1 - d R

Step-by-step explanation

We know that

h = 2 T cos θ ρ gr

∴    x = 2 T cos θ ρ gr

Now, value of geff  at depth 'd' is

g eff = g 1 - d R

∴    y = 2 T cos θ ρ g eff · r

∴    x y = g eff g = 1 - d R
