3A square boat of area = 2 m2 floats on the water with 1 m of boat submerged in the water. Estimate the buoyant force on the boat and the pressure at the bottom of the boat. The density of water is 997 kg/m3.
 
Fb = 30,000 N and P = 20,000 Pa
 
Fb = 10,000 N and P = 20,000 Pa
 
Fb = 100 N and P = 200 Pa
 
Fb = 20,000 N and P = 10,000 Pa
