A kg girl wearing high heel shoes balances on a single heel. The heel is circular with a diameter of . What is the pressure exerted on the horizontal floor?
Options
- A
- B
- C
- D
Correct answer
A.
Step-by-step solution
Given, mass of girl (m) = 50 kg
Diameter of circular heel (2r) = 1.0 cm
Radius (r) = 0.5 cm
= 5 × 10-3 m
Area of the circular heel (A) = πr2
= 3.14 × (5 × 10-3)2 m2
The pressure exerted on the horizontal floor
