Explanation:

rod b will sink less because rod b have large surface area Therefore pressure will be reduce.hence rod b will sink less

Answer 2

Answer:

Pressure(P)

$= \frac{force \: (f) }{area \: (a)}$

The rod A having more area of contact compared to rod B,and the forces is same because of same weight of the rods. Therefore the rod B will exert more pressure on that area than rod A. Hence,the rod B will sink more.
