A boat carrying a large number of stones is floating in a water tank. What will happen to water level if the stone are unloaded into water?

A

increase

B

remains same

C

decreases

D

data is insufficient

Text Solution

Verified by Experts

The correct Answer is:
C
Let weight of boat = W and weight of stone =w
Assuming density of water `=1 gc c^(-1)`
Volume of water displaced initially =(w+W)
Later, volume displaced `=(W+(w)/(rho)) (rho`= density of stones)
`implies` Water level comes down.
