Height of level of mercury in the left container is

Pressure at the bottom of left container is

Height of level of mercury in right container is

Pressure at the bottom of right container is

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION.

(a, b, c)

ρ Hg > ρ W

P A = P B

⇒ ρ w g h w + ρ Hg g H = ρ Hg g (1 – H)

⇒ H =

P A = P B = ρ Hg g (1 – H) = ρ Hg

g = g

1 – H = 1 – =
