Question

a hammer exist a force of 1.5 N on the nail. the area of cross section of tip of nail is 2mm2 calculate the pressure of Nail​

Answer 1

Explanation:

on A,

force = 1.5 N

area = 2 mm^2

1 mm = 1/1000 m = 0.001m 1 mm^2 = 1 mm*1mm = 0.001 m * 0.001 m = 0.000001 m^2 = 10^-6 m^2

P = 1.5N/(2*10^-6) m^2 = 7.5*10^5 Pa on B, P = 1.5N/(6*10^-6) m^2 = 2.5*10^5 Pa
