Answer:
Explanation:
The girl exerts more pressure on the force , because if the surface area decreases , pressure increases
Mathematically
Pressure =Force /Area
Force = Mass x acceleration
Force of girl = 90 x 10 =900 N
Pressure exerted by girl = 900/0.0001
9,00,00,000 Pa is exerted by girl
Elephant force = 3000 x 10 = 30,000 N
30,00/0.0025
1,20,00,000 Pa

girl exerts less pressure on the floor
P = Force/Area
if area is less pressure is less
girl occupies less area where as elephant takes more area
that is why girl exerts less pressure on floor
