Question

how much pressure will man of mass 50 kg exerts on the ground when he is standing (i)on both the foot (ii) on one foot given that area of one foot is 70 cm square. take g=9.8​ (please write the complete solution)​

Answer 1

pressure= force/area [FORCE=Mg]

[1] Pressure = mass*gravity/area

50*9.8/70+70 = 3.5 pascal

[2] pressure= 50*9.8/70 = 7 pascal

Answer 2

On one foot - 7000 pascals

On both foot - 3500 pascals

Hope it helps
