Question

A cube of side 50cm is placed at the bottom of a tank filled by water to a depth of 3m. Patm= 105 pa PL= 103kg/m3the pressure due to column of liquid at point A is

Answer 1

Answer & Explanation:

Given,

Side of Cube = 50cm

Water Depth = 3m

Atmospheric Pressure = 10⁵ Pa

Density = 10³ kg/m³

Gravitational Force = 9.8 m/s²

= Pressure = Atm. Pressure + hpg

= 100000+[3*1000*9.8]  Pa

= 100000+29400  Pa

= 129400 Pa

Or,

= 1.2*10⁵ Pa

Hope this helps.
