A pipe is sealed at one end and contains gas, which is confined by a column of water. The atmospheric pressure is $1.0 \times 10^{5}\ \text{Pa}$. The density of water is $1000\ \text{kg m}^{-3}$. Calculate the pressure of the gas. (Use $g = 10\ \text{m s}^{-2}$.)
- A$0.3 \times 10^{5}\ \text{Pa}$
- B$0.5 \times 10^{5}\ \text{Pa}$
- C$1.5 \times 10^{5}\ \text{Pa}$
- D$1.7 \times 10^{5}\ \text{Pa}$
