A) 80kg
B) 50kg
C) 60kg
D) 30kg
Correct Answer: A
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 \[=V{{d}_{water}}\] \[=0.2\times {{10}^{3}}=200\text{ }kg\] Hence, the additional weight which is supported by raft \[=200\text{ }kg-120\text{ }kg=80\text{ }kg\]You need to login to perform this action.
