Question

Total force acting on the surface of submarine
22. A metal plate of length 1.5 m and width 0.2 m is placed 40 cm below alcohol of density 800 kg m . If the
atmospheric pressure is 80 cm of mercury, calculate the force experienced by the plate. [Density of mercury
is 13,600 kg mand g = 10 ms?).
Ans.
Surface area of plate 1.5 m X 0.2 m = 0.3 m2​

Answer 1

Answer:

Therefore force acting on plate=PxA=1, 12,000x0.3=33, 600N
