Question

See the pic and answer me with a good explanation

Answer 1

Explanation:

Let us assume that , if the level of narrow tube goes down by h1

then,

wider tube goes up by h2

then,

volume decreases in case of narrow tube = volume increases in case of wider tube

Let radius of narrow tube is r

then, radius of wider tube is 4r

so, πr²h1 = π(4r)²h2

h1 = 16h2..........(1)

now, pressure at point A = pressure at point B

hpg = ( h1+ h2 )p'g

because specific density , s = p'/p

so, h = (h1+h2)8

h = 16h2 + h2

h2 = h/17↓8

=> 70/ 17×13.6

=> 0.3cm
