The pressure exerted by water (density = 10³ kg/m³) on the bottom surface of tank having dimensions 2m long, 4m broad, 2m deep is

 

• 1.9 × 10⁵ Pa
• 1.80 × 10⁴ Pa
• 2.96 × 10⁴ Pa
• 1.96 × 10⁴ Pa

Hello!

The Pressure (P) exerted by a liquid (here water) in a container of height (or depth h) and density (ρ) is 

   P = hρg

as per the question

h = 2m

ρ = 10³ kg/m³

g = 9.8 m/s

by putting the values, the calculated pressure would be

  P = 19.6 X 10³ Pa or 1.96 X 10⁴ Pa

which would be option (D).
