Explanation:
Weight of Suti = 600N
Area of her each foot = 150 cm^2
So, the pressure exerted by her when she stands on one foot on the ground = weight /area
= 150N/150cm^2
= 1N/cm^2
Again, the pressure exerted by Suti on the ground when she stands on two feet = Weight/ Area of 2 feet
= 150N/150×2cm^2
= 1/2 N/cm^2
= 0.5N/cm^2
