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
