A camel weighs 20,000 N. The area of its foot is `100 cm^2`. How much pressure does it exert on the ground by its single foot ?
Text Solution
Verified by Experts
The correct Answer is:
`5xx10^(5)" Pa"`
W=20,000 N Weight acting at its single foot `=(20,000)/(4)=5000N` Area `=100" cm"^(2)=10^(2)xx10^(-4)m^(2)` `=10^(-3)m^(2)` Pressure `=("weight")/("area")=(5000)/(10^(-2))` `=5xx10^(5)" pa"`
