    Answer:

    The magnitude of V_{2} is 4 V and phase of input voltage is zero

    Explanation:

    Given:

    Output voltage V_{out} = 17.33

    Resistance R_{1} = 3 kΩ

    Voltage gain A_{v} = 4.33

    For finding feedback resistance we use gain equation

    Gain equation for non inverting op-amp is given by,

         A_{v} = 1+\frac{R_{f} }{R_{1} }

       4.33 = 1+ \frac{R_{f} }{3 k }

         R_{f} ≅ 10 kΩ

    For finding input voltage we use,

       A_{v} = \frac{V_{out} }{V_{2} }

        V_{2} = \frac{17.33}{4.33}

        V_{2} = 4 V

    The Phase of V_{2} is zero because output voltage phase is 360°

    Therefore, the magnitude of V_{2} is 4 V and phase of input voltage is zero
