6. What force must you exert on a ball point pen in order to apply a pressure of .08 N/mm?
on a piece of paper, it the ball of the pen has a surface area of 1.22 mm² touching the
paper?

Respuesta :

  • Area=1.22mm^2=0.00001m^2
  • Pressure=0.8Pa

[tex]\\ \sf\longmapsto Force=Pressure(Area)[/tex]

[tex]\\ \sf\longmapsto Force=0.00001(0.8)[/tex]

[tex]\\ \sf\longmapsto Force=0.000008N[/tex]
