Question

Column I A If swimmer can swim at 5m sec in still water and if velocity of water flow is 4m sec then angle between direction of swimming and direction of river flow to minimize drift B If swimmer can swim at 5m sec in still water and velocity of flow is 3m sec then angle between direction of velocity of swimmer with respect to river and the direction of river flow if swimmer crosses the river in minimum time C If swimmer can swim at 4 m sec and velocity of flow is 3m sec then angle of resultant velocity w r t ground with the direction of river flow if swimmer heads perpendicular to flow of river P Angle between direction of fluttering of flag and north if wind blows towards south west direction with a velocity 3 2 m sec Man moves with a velocity 7m sec along west holding flag in his hand P 53 Q 127 R 143 S 90
