If for the complex numbers `z_1` and `z_2`, `|z_1+z_2|=|z_1-z_2|`, then `Arg(z_1)-Arg(z_2)` is equal to

If for the complex numbers z_(1) and z_(2)|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 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 are two nonzero 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 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) are two non-zero complex numbers such that |z_(1)+z_(2)|=|z_1|+|z_(2)| , then arg ((z_1)/(z_2)) is equal to

If for complex numbers z_(1) and z_(2) , arg z_(1)-"arg"(z_(2))=0 then |z_(1)-z_(2)| is equal to

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
