A raft of wood of mass 120 kg floats in water. The weight that can be put on the raft to make it just sink, should be $(d_{raft} = 600 kg / m^{3})$

Options:

Answer:

Solution:

Volume of raft is given by $V = \frac{m}{d} = \frac{120}{600} = 0.2 m^{3}$ If the raft is immersed fully in water. Then weight of water displaced is $= V d_{water}$ $= 0.2 \times 1 0^{3} = 200 kg$ Hence, the additional weight which is supported by raft $= 200 kg - 120 kg = 80 kg$
