Question

an elephant weight is 200 kg and foot are of a cross section of 200 CM Standing On The Floor find out the pressure exert by the elephant on the floor

Answer 1

pressure=force/area

pressure exerted by one foot = mg/area

P=200×9.8/(.002)²
1m=1/1000km
so 200cm =2m
and 2m=.002km

P=1960/.000004
P=49×10^8 pascal

so by four foot,
196×10^8pascal

Answer 2

we know that, pressure=force/area

here pressure exerted by one foot=mg/a^2

200×9.8/(0.002)^2

200cm=0.002km

49×10^8 Pascal

now , force exerted by elephant=49×4×10^8=196×10^8 Pascal
