Question

When Jenny writes the pencil exerts a force of 5N on the paper 

The Area of the pencil in contact with the paper is 0.5 mm² calculate the pressure of the pencil on the paper 
Give the Unit.

Answer 1

`Formula\ for\ pressure:\\\\ pressure=(Force)/(Area)\\\\unit\ of\ pressure[(N)/(m^2)=Pa] Force=5N\\ Area=0,5mm^2=0,0000005m^2\\\\ pressure=(5N)/(0,0000005m^2)=10000000Pa=10MPa\\\\ Pressure\ of\ the\ pensil\ on\ the\ paper\ is\ equal\ to\ 10MPa.`
