Answer #1

First, we convert the pressure into its S.I unit, the pascal.

Therefore,

This is the required pressure.

The formula to calculate the pressure exerted by a column of liquid is

where is the height of the column in metres

is the density of the liquid in , which is in the case of mercury

and is the acceleration due to gravity.

Substituitng our values, we get

Solving for , we get
