There are two holes one each along the opposite sides of a wide rectangular tank. The cross-section of each hole is 0.01 m^2 and the vertical distance between the holes is 1 m. The tank is filled with water. The net force on the tank in newton when the water flows out of the holes is (Density of water = 1000 kgm^(-3) )
