A) 100 N
B) 80 N
C) 50 N
D) 20 N
Correct Answer: D
Solution :
[d] Volume of block \[=\frac{8}{0.8\times {{10}^{3}}}={{10}^{-2}}{{m}^{3}}\] U = upthrust = weight of water displaced \[={{10}^{-2}}\times {{10}^{3}}\times 10=100\text{ }N\] w = weight = 80 N \[{{T}_{ension}}=U-W=100N-80N=20N\]You need to login to perform this action.
