A) \[2.7\times {{10}^{10}}J\]
B) \[9.9\times {{10}^{10}}J\]
C) \[10.8\times {{10}^{10}}J\]
D) \[5.4\times {{10}^{10}}J\]
E) zero
Correct Answer: B
Solution :
\[W=\frac{1}{4\pi {{\varepsilon }_{0}}}(1\times 2+2\times 3+3\times 1)\left( \frac{1}{0.5}-\frac{1}{1} \right)\] \[=9\times {{10}^{9}}\times 11\times 1\] \[=9.9\times {{10}^{10}}\]You need to login to perform this action.
