A rectangular tank contains water to a depth of 2m, if the base is 4m x 3m, calculate the force on the base (Density of water = 103kgm-3, g = 10ms-2)
1.4 x 102N
24 x 104N
2.0 x 104N
1.7 x 103N
설명
Volume = 2 x 4 x 3 = 24m3
mass = V x D = 24 x 103
F = mg
= 24 x 103 x 10
= 24 x 104
mass = V x D = 24 x 103
F = mg
= 24 x 103 x 10
= 24 x 104
