there are two holes one each along the opposite sides of wide rectangular tank.the cross section of each hole is 0.01 m and the vertical distance between two holes is one metre.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)

Bernoulli's equation will give us the speed of water coming out the hole

(density)×g×h + Patm + 0 = (density)×g×0 + Patm + (1/2)×(density)×(v^2)

h=1m. density =1000kgm^-3

v = √(20)m/s

Force exerted by water coming out is

F=(density)×(area of hole)×(v^2)

area of hole =0.01m^2

F = 200 N
