Three rigid buckets, shown as in the figures (1), (2) and (3), are of identical heights and base areas. Further, assume that each of these buckets have negligible mass and are full of water. The weights of water in these buckets are dented as W₁, W₂ and W₃ respectively. Also, let the force of water on the base of the bucket be denoted as F₁, F₂ and F₃ respectively. The option giving an accurate description of the system physics is

1. W₂ = W₁ = W₃ and F₂ > F₁ > F₃
2. W₂ > W₁ > W₃ and F₂ > F₁ > F₃
3. W₂ = W₁ = W₃ and F₁ = F₂ = F₃
4. W₂ > W₁ > W₃ and F₁ = F₂ = F₃

Correct Option: D

The buckets have same height and base area.
From the figure it is clear that,
W₂ > W₁ > W₃
Force at base = γ_w⋅h × A
Since, γ_w,h and A is same for all buckets,
F₁ = F₂ = F₃
