A cube (side `=10 cm`) of density `0.5 g//cm^(3)` is placed in a vessel of base area `20 cmxx20 cm`. A liquid of density `1.0 g/ cm^(2)` is gradually filled in the vessel at a constant rate `Q=50 cm^(3)//s`
If we plot a graph between the normal reaction on cube by the vessel versus time. The graph will be like
A.
B.
C.
D.
