A craft worker presses a flat-ended stamp against modelling clay. The normal force on the clay is 24 N and the contact area is 0.0060 m2. Use P=FAP=\dfrac{F}{A}P=AF.
Calculate the pressure exerted on the clay.
The normal force stays the same, but the contact area is doubled. State what happens to the pressure.
