Question

When we walk on sand, our feet sink into it and it is difficult for us to walk, but a camel can easily walk on it because:
(i) The weight of the camel is spread over a large area covered by its feet.
(ii) The pressure exerted by the camel’s body on the sand is large.

• A. Only (i) is correct
• B. Only (ii) is correct
• C. Both are correct and (ii) is the conclusion of (i)
• D. Both are correct and (i) is the conclusion of (ii)

Answer 1

The correct option is A Only (i) is correct

We know that pressure is inversely proportional to the surface area of the contact at which the force is acting. The camel’s feet have a larger surface area than our feet. So, the pressure exerted by camels is less than humans, and hence, they can walk easily on sand, unlike us.
