Question

A 5kPa pressure exerted on a cube of area 10cm square.calculate the force applied on the cube

Answer 1

Answer:

force=prssre*area=5*1000*10*0.0001-5N

Answer 2

The force applied to the cube is 5 N.

Given:

Pressure, P = 5 kPa

Area, A = 10 cm²

To Find:

The force applied to the cube.

Solution:

We are required to find the force applied to the cube.

The pressure and the force relation is given as

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

Force, F = Pressure×Area   -------(1)

We are given

Pressure(P) = 5 kPa

Pressure(P) = 5×10³ Pa

Area(A) = 10 cm²

Area = 10×10⁻⁴ m²

Area = 10⁻³ m²

Substitute the values of pressure(P) and area(A) in equation(1) we get

Force, F = 5×10³× 10⁻³  Pa/m²

Force, F = 5 N

Therefore, The force applied to the cube is 5 N.
