Question

An elephant weighing 240 kg is standing on three legs.If the surface area of each foot is 20 cm square.than the pressure exerted by elephant on the floor is

a) 30 00 000 N
b) 25 00 000 N
c) 40 00 000 N
d) 20 00 000 N​

Answer 1

GiveN :-

• An elephant weighing 240 kg is standing on three legs .
• The surface area of each foot is 20 cm².

To FinD :-

• The pressure exerted by elephant on the floor .

SolutioN :-

Given that a elephant standing on three legs having a weight of 240 kg has a surface area of 20 cm² of each foot . We need to find the Pressure . We know that the force acting per unit area is called Pressure . So , area of one foot is 20 cm² therefore the area of 3 feet will be 60 cm² . So that ,

$\red{\bigstar}\underline{\textsf{ Using the Formula of Pressure :- }}$

$\sf\dashrightarrow \pink{ Pressure=\dfrac{Force}{Area}}\\\\\sf\dashrightarrow P = \dfrac{Weight}{60 cm^2 } \\\\\sf\dashrightarrow P = \dfrac{240 kg}{\frac{60}{10000 } m^2 } \\\\\sf\dashrightarrow P=\dfrac{240\times 10^4 }{ 60 } Pa \\\\\sf\dashrightarrow \underset{\blue{\sf Required\ Pressure }}{\underbrace{\boxed{\pink{\frak{ Pressure = 4\times 10^4 \ Pascal }}}}}$
