z1 and z2 are any two distinct complex numbers in an argand plane. If αβ |z1|=γδ|z2|,
then the complex number lies on the (α, β ϵ R)
line segment [−2,2] on the real axis
line segment [−2,2] on the imaginary axis
unit circle |z|=1
None of these
A complex number z is said to be unimodular, if |z|=1. If and z1 and z2 are complex numbers such that z1−2z22−(z1¯z2) is unimodular and z2 is not unimodular. Then, the point z1 lies on a
