    Why is a slight blow on a cork of bottle filled with a liquid sufficient to break the bottle?

    Answer:

                    The blow on the cork exerts a pressure  \[(=f/a)\]on the liquid. According to Pascal's law, this pressure is transmitted to the entire bottle through the liquid. Since the surface area (A) of the bottle is large, the large force \[(=fA/a)\] so developed is sufficient to break the bottle.
