Question

4. A force of 200 N can produce a pressure of 20000 Pa. Calculate the area in cm2 on which the force
shall act to exert the pressure.
5. Calculate the magnitude of force required in newton to produce a pressure of 28500 Pa on an area
of 100 cm
moighe 50 N The area of contact of his two feet is 10 cm2. What pressure does he exert​

Answer 1

Answer:

4. p=f/a

20000=200/a

thus area=1/100 m^2

=100cm^2

5.pressure = force / area

force = pressure * area

force = 28500 pa / (100^2) cm2

force = 28500 Nm^(-2)/100 m^2

force = 285 N
