MCQ
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?
  • ✓
    No change
  • B
    It will rise
  • C
    It will fall
  • D
    It may rise or fall depending on the density of block
✓

Answer

Correct option: A.
No change
a
(a)Since no change in volume of displaced water takes place, hence level of water remains same.
