A) 80 kg
B) 50 kg
C) 60 kg
D) 30 kg
Correct Answer: A
Solution :
Volume of raft is given as \[V=\frac{m}{d}\] Here, \[m=120kg,\,d=600kg/{{m}^{3}}\] \[V=\frac{120}{600}=0.2{{m}^{3}}\] Where the raft is immersed fully in water then weight of water displaced is \[{{W}_{original}}=V{{d}_{water}}\] \[\Rightarrow \] \[{{W}_{original}}=0.2\times {{10}^{3}}=200kg.\] Clearly, the additional weight, which can be put on the raft.You need to login to perform this action.
