A) \[-\left( 3+\sqrt{8} \right)only\]
B) \[-3+\sqrt{8}\,\,only\]
C) \[-\left( 3+\sqrt{8} \right)\,\,or\,\,\left( -3+\sqrt{8} \right)\]
D) \[-\sqrt{8}\]
Correct Answer: C
Solution :
\[\frac{K{{Q}_{1}}{{Q}_{2}}}{{{d}^{2}}}\,\,=\,\,\frac{K{{\left( \frac{{{Q}_{1}}+{{Q}_{2}}}{2} \right)}^{2}}}{{{d}^{2}}}\] \[{{({{Q}_{1}}+{{Q}_{2}})}^{2}}=\,\,4{{Q}_{1}}{{Q}_{2}}\]You need to login to perform this action.
