A girl weighting 50kg is standing on pencil heels.Each having an area of cross section 1cm square.An elephant weighting 200kg and foot area with a cross section of 250 cm square is standing on the floor. Which of the two exerts more pressure on the floor?(given acceleration due to gravity=10m/s square)

Pressure = Force / Area.
Force = mass × accelaration.
in case (i);
m=50kg,a=10
so,F=ma=(50)(10)=500 N
•°•Pressure = 500/0.1=5000 Pascals.(0.1m=10cm)
case (ii);
m=200kg,accelaration=10,Area=2.5m
so F=(200)(10)=2000 N
P= 2000/2.5=800 Pascals
So, The girl is making more pressure than the elephant.
THANK you!!☺️
