The pressure will support a column of mercury whose vertical height is 760mm.
The term mm Hg means millimeters of mercury; this is a measurement of barometric pressure (the pressure of air is measured in terms of the equivalent height of a column of mercury that would exert the same pressure). 1 mmHg is about 133 pascals.
Water column head is expressed either as the height of the column ... 6 meters here ... or else as the pressure at the bottom ... 58.842 kPa here. 'Kg' can't be a unit of water column head, and the diameter of the column is irrelevant.
Surface area of a cylinder (the column) = pi*diameter*height and measured in square units.
the atmospere can not support the greater height column and the column of mercury will drop to the level in which the atmospere can support

The height of the Mercury column would decrease.
When air pressure increases, the mercury in a barometer rises.
The height of the Mercury column would decrease.
