A circular plate of radius 750 mm and area 1.767 × 106 mm2 is placed vertically in the water in such a way that the distance between the free surface of water and centre of the plate is 3000 mm. Assume density of water is 1000 \(\rm \frac{kg}{m^2}\) and acceleration due to gravity is 9.81 \(\rm \frac{m}{s^2}\). The total hydrostatic pressure force acting on the circular plate is:
1
45010.15 N
2
52002.81 N
3
45010.15 kN
4
52002.81 kN
