A) \[-G\]
B) \[-\frac{8}{3}G\]
C) \[-\frac{4}{3}G\]
D) \[-4G\]
Correct Answer: D
Solution :
\[V=-2G\left[ \frac{1}{1}+\frac{1}{2}+\frac{1}{4}+\frac{1}{8}- \right]\] \[=-2G\left[ 1+\frac{1}{2}+\frac{1}{{{2}^{2}}}+\frac{1}{{{2}^{3}}}... \right]\] \[=-2G\frac{1}{\left( 1-\frac{1}{2} \right)}=-4G\]You need to login to perform this action.
