A container of area 0.02 ${{m}^{2}}$ is 'filled with water

A container of area 0.02 ${{m}^{2}}$ is 'filled with water. Find the pressure at the > bottom of the container if a weight is placed on the piston, (as shown in the figure).

The net force acting on the base = (ρgh)A + mg
F = 1000 x 9.8 x 1 x 0.02 + 1 x 9.8
= 2 x 9.8 x +9.8 = 29.4 N
Pressure = thrust / Area = 29.4 / 0.02 = 1470 Pa
