Question

A cube of edge length 5 cm is placed inside a liquid. The pressure at the centre of a face is 12 pascal.find
the force exerted by the liquid on this face.​

Answer 1

Explanation:

area of surface on which the thrust acts = a²

[pressure is applied only on one face of the cube]

area=(5)²=25cm²

therefore,

$force = pressure \times area \\ = 12 \times 25 \\ = 300 \:newton$
