The apparent loss in weight is equal to the upthrust on the body verifies :

1. Pascal's law
2. Newton's third law
3. Archimedes' principle
4. Newton's second law

If a body is completely immersed in a liquid, the volume of the liquid displaced will be …………… its own volume and the upthrust will be ……………

1. less than, minimum
2. equal to, minimum
3. more than, maximum
4. equal to, maximum

The correct relation for upthrust on a solid of volume V immersed in a liquid of density ρ is :

1. F_B = $\dfrac{\text{V}_{\text{s}}}{\text{g}}$

2. F_g = $\dfrac{\text{ρg}}{\text{V}}$

3. F_B = Vρg

4. F_g = $\dfrac{\text{V}_{\text{g}}}{\text{ρ}}$

The S.I. unit of upthrust is:

1. Pa
2. N
3. kg
4. kg m²
