Question

A cube of density 0.5 g/cm³ is placed in vessel and a liquid of density 1 g/cm³ is gradually filled in the vessel at a constant rate then the graph representing variation of normal reaction of vessel on cube and time is –

• A. (a)
• A. (b)
• A. (c)
• A. (d)

Answer 1

(b)

Here force of buoyancy will act on cube when the liquid level

rises above it and it will rise up.
