What is the absolute pressure of the gas above the liquid surface in the tank shown in fig. Density of oil =820 kg / m 3, density of mercury =13.6 × 103 kg / m 3. Given 1 atmospheric pressure =1.01 × 105 N / m 2

Question

What is the absolute pressure of the gas above the liquid surface in the tank shown in fig. Density of oil =820 kg / m 3, density of mercury =13.6 × 103 kg / m 3. Given 1 atmospheric pressure =1.01 × 105 N / m 2 (A) 3.81 × 105 N / m 2 (B) 6 × 106 N / m 2 (C) 5 × 107 N / m 2 (D) 4.6 × 102 N / m 2

Correct answer is (a) 3.81 × 105 N / m 2

Q. What is the absolute pressure of the gas above the liquid surface in the tank shown in fig. Density of oil $= 820 k g / m^{3}$ , density of mercury $= 13.6 \times 1 0^{3} k g / m^{3}$ . Given $1$ atmospheric pressure $= 1.01 \times 1 0^{5} N / m^{2}$

$3.81 \times 1 0^{5} N / m^{2}$

$6 \times 1 0^{6} N / m^{2}$

$5 \times 1 0^{7} N / m^{2}$

$4.6 \times 1 0^{2} N / m^{2}$

Correct answer is (a) $3.81 \times 1 0^{5} N / m^{2}$
