Question

9.Calculate the thrust exerted by the liquid on the face of a cube of each side 4 cm placed inside a liquid. The pressure at the center of this face is 8 Pa.​

Answer 1

Answer:

1.28*10^-6

Explanation:

Given,

Pressure=8 Pa

Side of face of cube=4 cm= 0.04 m

Hence , area of face of cube= 0.04*0.04=0.0016 m².

We know,

Pressure= Force / Area

Or, 8= Force/0.0016

Or force= 8*0.0016

Or, force= 1.28*10^-6

Answer: Force is 1.28*10^-6
