A) \[\frac{1}{2}[|{{z}_{1}}{{|}^{2}}+|{{z}_{2}}{{|}^{2}}]\]
B) \[2[|{{z}_{1}}{{|}^{2}}+|{{z}_{2}}{{|}^{2}}]\]
C) \[2[|{{z}_{1}}{{|}^{2}}-|{{z}_{2}}{{|}^{2}}]\]
D) \[\frac{1}{2}[|{{z}_{1}}{{|}^{2}}-|{{z}_{2}}{{|}^{2}}]\]
Correct Answer: B
Solution :
\[|{{z}_{1}}+{{z}_{2}}{{|}^{2}}+|{{z}_{1}}-{{z}_{2}}{{|}^{2}}=2|{{z}_{1}}{{|}^{2}}+|{{z}_{2}}{{|}^{2}}]\]
