Assume that the point of projection and the edge of the boat are in the same horizontal level

Figure shows a liquid of densith 1200kgm^-3 flowing steadily in a tube of varying cross section. The cross section at a point A is 1.0cm^2 and that at B is 20mm^2 , the points A and B are in the same horizontal plane.The speed of the liquid at A is 10 cms^-1 . Calculate the difference in pressure at A and B.

Two balls having masses m and 2m are fasrtened to two light strings of same length (figure). The other ends of the strings are fixed at O. The strings are kept in the same horizontal line and the system is released from rest. The collision between the balls is elastic. Point A is the lowest point at which either ball can reach The speed of ball of mass 2m just after collision (for the first time) is over
