dL = FL / AY .....1 (i am representing delta by d)
=> 2 = mgL/AY = VDgL/AY where D is density of brick
again convert the equation 1 into delta...
d(dL) = (dF) L/AY
=>2 - (-0.6) = VKg L/AY where K is the density of water..
[note that force is changed by dF= VDg - (VDg - VKg) ]
divide both equations to get the answer...
