An ideal gas is trapped inside a test tube of cross-sectional area 20 cross times 10 to the power of negative 6 end exponent m to the power of 2 end exponent as shown in the figure. The gas occupies a height L1 at the bottom of the tube and is separated from air at atmospheric pressure by a mercury column of mass 0.002 kg. If the tube is quickly turned isothermally, upside down so that mercury column encloses the gas from below. The gas now occupies height L1 in the tube. The ratio fraction numerator L subscript 2 end subscript over denominator L subscript 1 end subscript end fraction is [Take atmospheric pressure = 10 to the power of 5 end exponent N m to the power of negative 2 end exponent]
