How is the pressure of 1000 N applied to a piston with an area of 0.2 m^2 calculated?

To determine how the pressure is calculated when a force is applied to a piston, it's important to understand the definition of pressure itself. Pressure is defined as the force applied per unit area. In this scenario, a force of 1000 N is applied to a piston with an area of 0.2 m². To calculate the pressure, you divide the total force (in this case, 1000 N) by the area over which that force is distributed (0.2 m²). This calculation yields the pressure exerted on the piston.

Mathematically, this is represented as:

[ \text{Pressure} = \frac{\text{Force}}{\text{Area}} ]

Thus, the correct approach to find the pressure in this example is indeed by dividing the force by the area, making this method accurate for calculating pressure in this context.
