Practice question
Question
A person stands on two bones, each with area 22cm2, exerting a total force of 588N. What is the average pressure on the bones?
Explanation
Pav = FA, F = 588N. Total area A = 2×22×10−4 = 4.4×10−3m2. Pav = 5884.4×10−3 = 1.33636×105Pa. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 1.34 × 10⁵ Pa. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
