Question

a vessel of base area 100 cm × 60cm and height 200cm is completely filled with a liquid of density

1.1×103

kgm-3

.

take g=9.8m/s2 . [4]

A. The thrust at the bottom of the vessel

B. The pressure at the bottom of the vessel

C. The pressure at a depth of 5 cm from the free surface

D.the net force experienced by a metal foil of area 10 cm2 placed at a depth of 5 cm from the free surface.

pls answer fast in need​

Answer 1

Answer:

Pressure =ρgh

where ρ=density of water

g=acceleration due to gravity

P=10

Upthrust = Force exerted = Pressure \times Area

⇒Upthrust=1.47×10
