    What will be the height of mercury column in a barometer, it it is taken to the moon?

    Answer:

    As P and d are same, height of the liquid column would be inversely proportional to each other. \[{{h}_{1}}{{g}_{1}}={{h}_{2}}{{g}_{2}}\] \[{{h}_{2}}=\frac{{{h}_{1}}{{g}_{1}}}{{{g}_{2}}}=\frac{76\times g}{{}^{g}/{}_{6}}=76\times 6=456\,cm\] The liquid column rises to 456 cm from 76 cm.
