Answer Posted / arun k s
The air introduced into the top of the barometer fills
evenly inside the barometer and excerts its pressure (which
further increases when the mercury colomn compresses the
air). Hence the inside mercury colomn get the assistance of
this air pressure to balance the outside atmospheric
pressure & the mercury level depresses.
