The pressure is 22.59 x 10⁵ Pa.

We need to know about pressure to solve this problem. Pressure is unit that describe how much force applied on a surface area. It can be determined as

P = F / A

where P is pressure, F is force and A is area.

From the question above, we know that

d = 0.39 cm = 0.0039 m

F = 27 N

Calculate the surface area of the nail

A = π . r²

A = π . (1/2 . d)²

A = π . (1/2 . 0.0039)²

A = 1.195 x 10¯⁵ m²

Determine the pressure

P = F / A

P = 27 / (1.195 x 10¯⁵ )

P = 22.59 x 10⁵ Pa

Hence, the pressure is 22.59 x 10⁵ Pa.
