A barometer is constructed using a liquid (density $=760 \mathrm{kg} {\mathrm{m}}^{-3}$) What would be the height of the liquid column, when a mercury barometer reads $76 \mathrm{cm}?$

(density of mercury $=13600 \mathrm{kg} {\mathrm{m}}^{-3}$)

• A

  $1.36 \mathrm{m}$
• Correct answer
  B

  $13.6 \mathrm{m}$
• C

  $136 \mathrm{m}$
• D

  $0.76 \mathrm{m}$

Hence, the correct answer is option: 'B'.
