The pressure exerted on a body is 10 Nm^-2, if the area of the body is 2 m² : then the thrust acting on the body will be: 

The Correct answer is 20 N.

Key Points

• Pressure is defined as the force exerted per unit area of a surface.
• The formula for calculating pressure is Pressure = Force/Area.
• In this case, the pressure is given as 10 N/m² and the area of the body is 2 m².
• To find the thrust (or force) acting on the body, we use the formula Thrust = Pressure × Area.
• Substituting the values into the formula: Thrust = 10 × 2 = 20 N.
• The thrust acting on the body is therefore 20 N, which corresponds to the correct option.
• Thrust is a term used to describe the total force exerted perpendicular to a surface.
• This concept is important in mechanics and fluid dynamics to understand the interaction between forces and surfaces.

 Additional Information

• Pressure
  • Pressure is measured in units of Newton per square meter (N/m²), also known as Pascals (Pa).
  • It is widely used in areas such as engineering, physics, fluid mechanics, and material science.
  • Pressure is a scalar quantity, meaning it has magnitude but no direction.
• Thrust
  • Thrust is a term used to describe the perpendicular force exerted by a body on a surface.
  • It is commonly discussed in the context of aerodynamics, fluid dynamics, and propulsion systems.
  • Thrust is measured in units of Newton (N), which is the standard unit for force in the International System of Units (SI).
• Area
  • Area is a measure of the surface covered by a shape or object.
  • It is expressed in square units such as m² in the SI system.
  • Understanding area is essential for calculations involving pressure, thrust, and energy distribution.
