Chapter 12, Problem 12.1DQ

A cube of oak wood with very smooth faces normally floats in water. Suppose you submerge it completely and press one face flat against the bottom of a tank so that no water is under that face. Will the block float to the surface? Is there a buoyant force on it? Explain.

Expert Solution & Answer

To determine

The state of the oak when it is completely submerged and press against bottom of a tank so that no water is under that face, and the present of buoyant force acting on the oak.

Explanation of Solution

Section 1:

To determine: The state of the oak when it is completely submerged and press against bottom of a tank so that no water is under that face.

Introduction: The buoyant force is the force exerted by the water on the submerged body.

The cubic oak submerged in water feels an upward exerted force exerted by the water. The exerted force on the oak by the water is known as buoyant force and this force causes the oak to float into the surface. But when the cubic oak is completely submerged under the water and press against the bottom of tank so that no water is under that face, there will be no buoyant force acting on the oak. It is because there is no water present in the bottom surface of the oak to generate buoyant force against it. Thus, the cubic oak will not float to the surface.

Conclusion: Therefore, the cubic oak will not float to the surface when it is completely submerged under the water and press against bottom of tank.

Section 2:

To determine: The present of the buoyant force acting on the cubic oak.

Introduction: The buoyant force is the force exerted by the water on the submerged body.

The buoyant force acting on an object is equal to the weight of the water displaced by the submerged object. But when the cubic oak is completely submerged under the water and press against the bottom of tank so that no water is under that face, there will be no buoyant force acting on the oak. It is because there is no water present in the bottom surface of the oak to generate buoyant force against it.

Conclusion: Therefore, there will be no buoyant force acting on the cubic oak when it is completely submerged under the water and press against bottom of tank.
