A) \[80\,\,kg\]
B) \[50\,\,kg\]
C) \[60\,\,kg\]
D) \[30\,\,kg\]
Correct Answer: A
Solution :
When a body is immersed partially or completely in a liquid, it experience an upthrust, which is equal to weight of the liquid displaced by it. Volume of raft\[=\frac{m}{d}=\frac{120}{600}=0.2\,{{m}^{3}}\] Weight of water displace\[=0.2\times {{10}^{3}}=200\,kg\] Hence, additional weight supported by raft is \[=200\,kg-120\,kg=80\,kg\]You need to login to perform this action.
