Question

Question 8
In a large commercial complex, there are four ways to reach the main road. One of the paths has loose soil, the second is laid with polished marble, the third is laid with bricks and the fourth has a gravel surface. It is raining heavily and Paheli wishes to reach the main road. The path on which she is least likely to slip is

(a) Granite surface
(b) polished marble
(c) Tile floor
(d) gravel

Answer 1

(d) gravel

She should use the gravel surface path which provides sufficient friction force to walk. Soft and wet sand greatly increases the amount of effort as we sink into them. Gravel on top of mud stops us sinking deeper. And that makes walking easier.
