Question

A boy is standing on a ground. The area below his feet is 60 cm2. pressure exerted on ground is 6 N/m2. Calculate the total force acting on the ground?

Answer 1

Answer:

pressure=force/area

6=f/60*$10^{-4}$

then F=6*60*$10^{-4}$

 F=3.6*$10^{-2}$N/m

Answer 2

Answer:

Explanation:

PRESSURE = FORCE / AREA

FORCE = PRESSURE * AREA

AREA = 60 cm² = 60 * 10⁻⁴ m²

FORCE = 6 * 60 * 10⁻⁴

             = 3.6 * 10⁻² N
