A) - 5
B) 15
C) 5
D) 25
Correct Answer: C
Solution :
Since the coordinates in complex plane are (2, 3) and \[(-1,\,-1)\] Hence the required distance is 5. Trick: We know that the distance between \[{{z}_{1}}\] and \[{{z}_{2}}\] is \[|{{z}_{1}}-{{z}_{2}}|\] therefore, the required length\[|2+3i+1+i|=5\].
