Question

How would the levels change in (b) if 13.6 cm of H₂O (immensible with mercury) are poured into the right limb of the manometer in the above numerical.

Answer 1

As h₁ p₁ g = h₂ p₂ g 

h₁ × 13.6 × g = 13.6 × 1 × g 

h₁ = 1 cm 

Therefore as 13.6 cm of H₂O is poured in right limb it will displace Hg level by 1 cm in the left limb, so that difference of levels in the two limbs will become 19 cm.
