Question

Iraq suspended by weighing scale weighs 3 N when submerged in water and 5 N went out of water what is the Buoyant force on the rock?a)8 N b)5 Nc)3 Nd)2 N

Answer 1

Given data

*The weighing scale submerged in water is 3 N

*The weighing scale submerged out of water is 5 N

The buoyant force on the rock is calculated as

`\begin{gathered} F_b=5-3 \\ =2\text{ N} \end{gathered}`

Thus, the buoyant force on the rock is 2 N
