Question

A block of wood is floating in a lake . The apparent weight of the floating block is

• A. equal to its true weight
• B. less than its true weight
• C. more than its true weight
• D. equal to zero

Answer 1

The correct option is D equal to zero

When we immerse any object in liquid$,$ an upward force called as upthrust acts on the object$,$ and simultaneously the weight of the body acts downward$.$

so$,$ when we immerse a block in water and it floats$,$ then the apparent weight of the block is equal to zero because the weight of the object acting vertically downwards is balanced the upward force called as upthrust$.$

Hence$,$ option $\left(D\right)$ is correct$.$
