Given:-
- 280 cm² = 280/10000 m² = 28/1000 m²
To be calculated:-
Calculate the pressure exerted on a level ground.
Formula used:-
Pressure = Force/Area
Solution:-
First of all,
We have to find out Force ;
Force = m × g
Force = 75 kg × 9.8 m/s²
Force = 735 kg.m/s² [ 1 N = kg.m/s² ]
Force = 735 N
Now,
Pressure = Force/Area
Pressure = 735 / 28/1000
Pressure = 735 × 1000 / 28
Pressure = 735000 / 28
Pressure = 26,250 Pascal
