प्रश्न
The base of the cylindrical vessel measures 300 cm2. Water is poured into it up to a depth of 6 cm. Calculate the pressure of water on the base in the vessel.
उत्तर
Area of base of cylinder = A = 300 cm2
A = 300 × 10 m2
A = 3 × 102 m2
Height (or depth) of water column = h = 6 cm
h = `6/100` m
Density of water = ρ = 1000 kg/m3
Acceleration due to gravity = g = 10 m/s2
Pressure at the base in vessel = P = hρg
ρ = `6/100xx1000xx10`
P = 600 Pa
