Chapter 14.2, Problem 13R

To determine

The way through which the fluid exerts forces on objects.

Explanation of Solution

Introduction:

Pascal’s law states that the pressure applied on any surface of the fluid, transmits in all directions with same intensity.

The fluids are made of molecules that are free to move in all directions. When pressure is applied on surface of the object, the molecules near that surface experiences same pressure. These molecules transfer this pressure to other molecules and transmit to other surfaces of the object.

Conclusion:

Thus, the fluid exerts the forces on the object due to the pressure transmits by the molecules.
