    Solution:

    Concept- Pressure and thrust respectively are 9800n N and 29400 N/meter sq. The force applied to a surface by a mass of water per unit area of surface is known as the water pressure at the bottom of a tank. The force that water applies downward and perpendicularly to the surface is known as the push.
    Liquid pressure, indicated by the letter "h," is dependent on the height of the water column (depth) .
    Density of liquid Acceleration due to gravity which equals to Thus, by using pressure formula
    We shall first determine the surface's area in order to determine the thrust operating on it.
    Area = length width
    Area Area Now we know that
    Pressure Thrust ( Force Pressure Area
    Now The result of substituting the pressure and area values from above is
    Thrust Thrust So, the Pressure at the bottom of the tank is and Thrust .
    Hence, the correct answer is 29400N.
