162- A vertical tube is held upright and mercury of height 4cm has been poured into it and at that height it has solidified. If the atmospheric pressure is $P_a = 0.336 \times 10^5 \, \text{Pa}$, by raising the mercury inside the tube by how many centimeters will the pressure in the two tubes become equal? $$\left(\rho_{\text{mercury}} = 13.6 \, \frac{\text{g}}{\text{cm}^3} \text{ and } g = 10 \, \frac{\text{m}}{\text{s}^2}\right)$$ (1) $84$ (2) $82$ (3) $80$ (4) $78$
