The upthrust is maximum (= F_B) when the body is:

1. floating in the liquid
2. completely immersed inside the liquid
3. partially immersed inside the liquid
4. None of these

When the weight of a body is greater than the weight of the liquid displaced, the body will

1. float
2. sink
3. float partially outside
4. first go down then come up

A body of weight W is floating in a liquid. Its apparent weight will be:

1. equal to W
2. less than W
3. greater than W
4. zero

For a floating body of volume V, the relation between the volume of its submerged part $v$, the densities of liquid (ρ_L) and the body (ρ_S) is :

1. $\dfrac{v}{V}$ = $\dfrac{ρ$s}{ρL}

2. $\dfrac{V}{v}$ = $\dfrac{ρ$s}{ρL}

3. $v \times ρ$s = V \times ρL

4. none of these
