A vertical barrier separates stationary water on its two sides. A small panel is mounted on the barrier, with water on both sides of the panel. Both water surfaces are open to the atmosphere. The pressure is uniform over the panel. Take g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg.
| Quantity | Value |
|---|---|
| Vertical height of water above the panel on side A | 2.4 m |
| Vertical height of water above the panel on side B | 1.6 m |
| Density of water | 1000 kg/m3 |
| Area of the panel | 0.30 m2 |
Calculate the resultant force exerted on the panel by the water.
