Question

Force of 35 N acts over an area of 7 square meters. Calculate the pressure.

Answer 1

Pressure = Force/Area

So P=35/7 which equal to 5N per square meter.

Answer 2

Concept:

Pressure: Pressure is defined as the force acting per unit area. Its SI unit is Pa (pascal) or Nm⁻². It is the ratio of the force to the area.

If a force of F N is acting on an object of area A m², then the pressure on the object is given by,

P = F/A

where P = Pressure

F = Force

A = Area

Given:

Force, F = 35 N

Area, A = 7 square meter = 7 m²

Therefore, Pressure (P) is given by,

Pressure (P) = Force(F)/Area (A)

P = F/A

P = 35 N/7 m²

P = 5 N/m²

P = 5 Nm⁻²

P = 5 Pa

Hence, the pressure is 5 Nm⁻² or 5 Pa.
