Question

How much pressure is exerted on the head of the nail when it is struck with a force of 50n. The area of cross section of the nail head is 0.00002meter square

Answer 1

Force applied on nail = 50 N

Area of the cross section of the nail = 0.00002 m²

= 2/100000

= 2 * 10 raised to -5

Pressure exerted on the nail = Force/Area

= 50/(2 * 10 raised to - 5)

= 25/10 raised to - 5 (1/a power -n = a power n)

= 25 * 10 raised to 5 Pascal

Pressure exerted on the nail is 25 * 10 raised to 5 Pascal
