A) 1
B) 1/2
C) 2
D) \[\sqrt{2}\]
Correct Answer: A
Solution :
\[\left( \frac{3+2i}{3-2i} \right)=\left( \frac{3+2i}{3-2i} \right)\left( \frac{3+2i}{3+2i} \right)\]\[=\frac{9-4+12i}{13}=\frac{5}{13}+i\left( \frac{12}{13} \right)\] Modulus =\[\sqrt{{{\left( \frac{5}{13} \right)}^{2}}+{{\left( \frac{12}{13} \right)}^{2}}=1}\].
