A liquid of mass 1.0 x 10³kg fills a rectangular tank of length 2.5m and width 2.0m. If the tank is 4m high, what is the pressure at the middle of the tank?[g = 10ms^-2]

1.0 x 10⁴Nm^-2

2.0 x 10³Nm^-2

1.5 x 10³Nm^-2

1.0 x 10³Nm^-2

Correct answer is D

Density of liquid = \(\frac{1 {\times} 10^3}{2.5 {\times} 2 {\times} 4}\)

= 50kgm³

pressure heg = 50 x 10 x \(\frac{4}{2}\)

= 1 x 10³Nm^-2
