easy
A rectangular block is $5 cm × 5 cm × 10cm$ in size. The block is floating in water with $ 5 cm $ side vertical. If it floats with $10 cm $ side vertical, what change will occur in the level of water?
A
No change
B
It will rise
C
It will fall
D
It may rise or fall depending on the density of block
Solution
(a)Since no change in volume of displaced water takes place, hence level of water remains same.
