Question

the pressure of a gas in LPG cylinder with a movable piston is 300Pa. the area of the piston is 0.5 metre square. calculate the force exerted on the piston.​

Answer 1

Solution-

Given,

• Pressure (P) = 300 Pa or 300 N/m²
• Area (A) = 0.5 m²

We know that, Pressure = Force/Area

So, Force = Pressure × Area

= 300 N/m² × 0.5 m²

= 150 N.

________________________________

• Force: A pull or push acting on a body which tends to change its state of rest of motion, or the direction of motion, or its shape or size.

• Moment of Force: The product of the magnitude of force and perpendicular distance of force from the pivot point.

• Pressure: The force acting on a unit area of a surface.
