Q)What is the apparent weight of the floation? And the answer given below why is it incorrect .I have said many times that "DO NOT SEND SIMILAR QUERIES"
Ans : Apparant weight of the flotation means the density of the body submerged in the fluid is equal to the upthrust.
That is body will float in the submerged fluid.
