A drawig pin is pressed into a notice board.
The pin is pressed into the notice board with force of 20N.
The head of the drawing pin has an area of 100nm squared.
1) What is the size of the force exerted by the point of the pin on the notice board?
2) Calculate the pressure exerted by the point of the drawing pin. Give the unit.

units for pressure is Pascal.

Thanks already knew that....hoping for a more detailed answer

Okk
the force which the point of pin exert on the drawing board
will be same as the force you are applying
that is 20N
so part a is 20N
for part B
using forumula;
Pressure =Force/area
we will get,
pressure = 2*10^15 pascal
(where 1 nm =10^-9 m)
will be same as the force you are applying
that is 20N
so part a is 20N
for part B
using forumula;
Pressure =Force/area
we will get,
pressure = 2*10^15 pascal
(where 1 nm =10^-9 m)
Got,it
thank you very much
Pls ! rate me as brainlest,to show your thanks
As I answered your question,in good way
