An ideal liquid of density 1gm/cc is flowing at a ratė of 10gm/s through a tube with varying cross-section, as shown in the figure. ITIFR 2012] B Two pressure gauges attached at the points A and B (see figure) show readings of P, and P, respectively. If the radius of the tube at the points A and B is 0.2 cm and 1.0 cm respectively, then the difference in pressure (P-P), in units of dyne cm2, is closest to (a) 100 b) 120 (c) 140 d) 160
