3. A rectangular gate is 2 meters wide and 3 meters tall. If it is submerged vertically in water to a depth of 5 meters, what is the hydrostatic force acting on one face of the gate? (Assume water density = 1000 kg/m³ and acceleration due to gravity = 9.81 m/s²)

1. 29430 N
2. 14715 N
3. 58860 N
4. 7365

Answer: C) 58860 N

Explanation:

The hydrostatic force is calculated as F = ρghA, where ρ = 1000 kg/m³, g = 9.81 m/s², h = 5 m, and A = 2 m * 3 m = 6 m². By substituting the values, we get F = 1000 * 9.81 * 5 * 6 = 58860 N.
