    Question

    If z=2+3i, then arg(z)=θ lies in which

    quadrant?
    A I Correct Answer Incorrect Answer
    B II Correct Answer Incorrect Answer
    C III Correct Answer Incorrect Answer
    D IV Correct Answer Incorrect Answer

    Solution

    We are given a complex number: z =2+ 3i We are to determine the quadrant in which the argument θ=arg(z) lies. The complex number z=a+bi=2+3i corresponds to the point (2,3) in the complex plane , where:

    • Real part = 2 (positive)
    • Imaginary part = 3 (positive)
    So, the point lies in the first quadrant , where both real and imaginary parts are positive.
