Question

animals a, b and c of same weight walk on a road. the ratio of area of the feet is 2:5:3, then what is the ratio of pressure exerted by them on the road.

Answer 1

Answer:

$2:5:3$

Explanation:

The pressure is the force per unit area. So, P=F/A

The board feet means more area. As the pressure is inversely proportional to area, so the more area will exert less pressure.

Thus, both assertion and reason are correct and reason is the correct explanation for assertion.
