Statement–I : Two identical conical pipes shown in figure have a drop of water. The water drop tends to move towards tapered end
Statement–II 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
