Two rods of the same weight and equal length have different thickness. They are held vertically on the surface of sand as shown in the figure. Which one of them will sink more? Why?

Solution

Rod B will go deeper. Both the rods have same weight, but the base area of rod B is less than that of A. Hence, the pressure applied by B on the sand is more than that of A. Hence, B sinks deeper.
