Problem

A column of mercury of length

10\,\text{cm}

is contained in the middle of a horizontal tube of length

1\,\text{m}

, closed at both ends. The two equal air columns are at standard atmospheric pressure, equal to

0.76\,\text{m}

of mercury. The tube is now turned vertical. By what distance, in cm, will the mercury column be displaced? Assume the temperature remains constant.
