A boat flaoting in a water tank is carrying a number of large stones. If the stones are unloaded into the water, what will happen to the water level in the tank
[ hint : Assume the initial level of the tank to be K and the length of the boat immersed in water to be h. Apply the law of floatition. find the volume of water in th tank. repeat the process after a plece of stone is unloaded. the stone will sink to the bottom .
assume the new height to be H' and h' respectively.
make use of the fact that the volume of water remains constant .
`H-H=V/A((P_(s))/(P_(w))-1)`
where V = volume of stone , A = area of cross - section of tank , `P_(s)` = density of stone and `P_(w)` = desnsity of water .]

Answer

the level will fall
