Question

The tip of a drawing pin has an area 5mm² find the pressure exerted if force applied is 10N

Answer 1

Answer:

10^9 N/m²

Step-by-step explanation:

P = F/A

given

F = 10N

A = 1.0×10^-8m²

hence,

P = 10/1.0×10^-8 N/m²

P = 10×10^8 = 10^9 N/m²

Answer 2

Answer

1m^2=1000mm*1000mm

or, 1m^2=10^6mm^2

therefore 1mm^2=10^6m^2..

that's why I have divided by 10^6..
