A) \[\frac{3|z{{|}^{2}}}{2}\]
B) \[\frac{3\sqrt{3}|z{{|}^{2}}}{2}\]
C) \[\frac{\sqrt{3}|z{{|}^{2}}}{2}\]
D) None of these
Correct Answer: B
Solution :
Let the point A represents the complex number z, B represents \[\omega z\] and C represents\[\bar{\omega }z\]. \[\omega \,\,\And \,\,\bar{\omega }\] are complex cube roots of unity clearly coz means rotation of z by \[\frac{2\pi }{3}\,\,and\,\,{{\omega }^{2}}z\] \[(=\bar{\omega }z)\] means rotation of \[\omega z\,\,by\,\,\frac{2\pi }{3}\]You need to login to perform this action.
