If Re `(lambda Z + (2)/(Z))` is zero and Re(z) `!= 0` and |Z| = 2. Then `lambda` can be

If z ne 0 and Re z=0 then

If z is purely real and Re(z) < 0, then Arg(z) is

Let z in C be such that Re(z^(2)) = 0 , then

Solve the system of equations Re(z^2)=0, |z|=2 .

Solve the system of equation Re(z^(2))=0,|z|=2 .

Solve the system of equations Re( z^2 ) = 0, abs(z) = 2

If |Z-2|=2|Z-1| , then the value of (Re(Z))/(|Z|^(2)) is (where Z is a complex number and Re(Z) represents the real part of Z)
