If z1,z2 are two nonzero complex numbers such that |z1+z2|=|z1|+|z2| then amp z1z2 is equal to

The correct option is A 0This is true if the the complex numbers are parallel.i.e. arg(z1)=arg(z2)Hence,arg(z1z2)=0

If $z_{1}, z_{2}$ are two nonzero complex numbers such that $| z_{1} + z_{2} | = | z_{1} | + | z_{2} |$ then amp $\frac{z_{1}}{z_{2}}$ is equal to

The correct option is A $0$
This is true if the the complex numbers are parallel.
i.e. $a r g (z_{1}) = a r g (z_{2})$
Hence, $a r g (\frac{z_{1}}{z_{2}}) = 0$
