Question

An actress of mass 50 Kg is wearing sharp-heeled shoes. If the area of one heel is 1 cm2, Calculate the pressure exerted on the ground when she stands on just one heel (g = 10 m/s2) [Ans. 5 × 106 Pa]

Answer

Mass (m) = 50 Kg

Area (A) = 1 cm2 = 10-4 m2

Step 1: Calculation of Force

Force (F) = Mass (m) × g

= 50 × 10 = 500 N

Step 2: Calculation of Pressure

Pressure (P) = Force\over Area

= 500\over 10^{-4}

= 5 × 106 Pascal
