QUESTION ---- A drawing pin is pushed against a wooden table with a force of 10 N. Calculate the pressure exerted by the pin at a point on the table, if area of the point is 0.01 mm 2 .
ANSWER
_____________________________
Pressure is Force applied per unit area.
IN THE QUESTION, IT IS GIVEN
Force = 10 N
Area = 0.01 mm^2
Convert Area in SI unit I.e. m^2
1 m^2 = 1000000 mm^2
Area = 0.01 / 1000000 m^2
______________________________
Pressure = Force / Area
Pressure = 10 / (0.01/1000000)
Pressure = 10 × 1000000 / 0.01
Pressure = 10000000 / 0.01
Pressure = 1000000000 Pascal
Pressure = 10^9 Pascal
______________________________
ANSWER = 10^9 Pa
