A) \[8\times {{10}^{5}}J\]
B) \[16\times {{10}^{5}}J\]
C) \[12\times {{10}^{5}}J\]
D) \[32\times {{10}^{5}}J\]
Correct Answer: B
Solution :
Work \[W=mgh+\Delta pV\] \[=Vpgh+ApV\] \[=4\times {{10}^{3}}\times 10\times 20+(2\times {{10}^{5}}\times 4)\] \[=16\times {{10}^{5}}J\]You need to login to perform this action.
