Question

The area of the point tip of pin 0.01cm^2 .Your pushing force on the head of the pin is 20N. Find pressure?

Answer 1

#AlexaRousey here!!

Given :
Area = 0.01 cm^2
= 0.01 * 10^-4 m^2
= 10^-6 m^2

Force = 20N

Pressure = F/A

= 20/10^-6 Pa

= 20* 10^6 Pa

= 2 * 10^7 Pa

Thanks!!

Answer 2

Applied force = 20N
Area = 0.01cm² = 0.01/10000 m²

Pressure
= Force/Area
= 20x1000/0.01
= 20000000 N/m²
i.e.,2x10^7 N/m²
