If `z_1, z_2` are complex number such that `(2z_1)/(3z_2)` is purely imaginary number, then find `|(z_1-z_2)/(z_1+z_2)|` .

If z_1,z_2 are complex numbers such that, (2z_1)/(3z_2) is purely imaginary number then find |((z_1-z_2)/((z_1+z_2))| .

If z_1,z_2 are comples numbers such that (2 z_1)/(3z_2) is purely imaginary number, then find |(z_1-z_2)/ (z_1+ z_2)| .

If z_(1), and z_(2) are complex numbers,such that (3z_(1))/(2z_(2)) is purely imaginary,then find |(z_(1)+z_(2))/(z_(1)-z_(2))|]|

If 2z_(1)/3z_(2) is a purely imaginary number,then find the value of |(z_(1)-z_(2))/(z_(1)+z_(2))|

If 2z_1//3z_2 is a purely imaginary number, then find the value of "|"(z_1-z_2")"//(z_1+z_2)|dot

If 2z_1//3z_2 is a purely imaginary number, then find the value of "|"(z_1-z_2")"//(z_1+z_2)|dot

If 2z_1//3z_2 is a purely imaginary number, then find the value of "|"(z_1-z_2")"//(z_1+z_2)|dot

If (2z_1)/(3z_2) is purely imaginary then |(z_(1)-z_(2))/(z_(1)+z_(2))|
