If `z_1 and z_2` are two non - zero complex numbers such that `|z_1+z_2|=|z_1|+|z_2|` then `Argz_1-Argz_2` is

If z_1 and z_2 are two non - zero complex numbers such that |z_1+z_2|=|z_1-z_2|, then Argz_1-Argz_2 is

If z_1 and z_2 are two non zero complex number such that |z_1+z_2|=|z_1|+|z_2| then arg z_1-argz_2 is equal to (A) - pi/2 (B) 0 (C) -pi (D) pi/2

If z_1 and z_2 , are two non-zero complex numbers such tha |z_1+z_2|=|z_1|+|z_2| then arg(z_1)-arg(z_2) is equal to

If z_1 and z_2 be two non-zero complex numbers such that |z_1+z_2|=|z_1|+|z_2| ,then prove that argz_1-argz_2=0 .

If z_(1)" and "z_(2) are two non-zero complex numbers such that |z_(1)+z_(2)|=|z_1|+|z_(2)| , then arg z_(1)- arg z_(2) is equal to

If z_(1) and z_(2) are two nonzero complex numbers such that =|z_(1)+z_(2)|=|z_(1)|+|z_(2)|, then argz_(1)-arg z_(2) is equal to -pi b.-(pi)/(2) c.0d.(pi)/(2) e.pi

If z_(1) and z_(2), are two non-zero complex numbers such tha |z_(1)+z_(2)|=|z_(1)|+|z_(2)| then arg(z_(1))-arg(z_(2)) is equal to
