Statement-1: Two identical conincal pipes shown in figure have a drop of water. The water drop tens to move towards tapered end.
Statement-2: Excess pressure is directed towards centre of curvature and inversely proportional to radius of curvature. Net excess pressure is therefore, directed towards tapered end. So the water drop tends to move towards tapered end.
