Question: The piston ( Figure 2 ) has fluid on both sides. The gage pressure below the piston P 1 = 3 0 kPa and the

The piston (Figure 2) has fluid on both sides. The gage pressure below the piston P1=30kPa and the absolute
pressure above the piston P2=90kPa. What force F must be applied to the piston to keep it stationary? The diameter
D=6cm. Neglect the magnitude of the force due to Patm acting on the rod relative to the magnitude of the force due to
P2 acting on the piston.
Express your answer in N to three significant figures.
