Question

A body of weight $1\mathrm{k}\mathrm{g}\mathrm{f}$ is floating in the water what is the apparent weight of the body in water?

Answer 1

Step 1: Given,

Weight of the body floating in the water, $W$ = $1\mathrm{k}\mathrm{g}\mathrm{f}$ = $9.8N$

Step 2: Formula used,

Weight of floating body = weight of water displaced

Apparent weight of the body is given by, $W_{apparent}=W-F_b$

Where $W$ is the weight of the floating body and $F_b$ is the buoyant force.

Step 3: Calculation,

$$\begin{gathered} W_{apparent}=9.8-9.8 \\ =0 \end{gathered}$$

Hence, apparent weight of the body in water is 0.
