Consider the circuit shown in the figure. In this circuit $$R = 1\,\,k\Omega ,$$ and $$C = 1\,\,\mu F.$$ The input voltage is sinusoidal with a frequency of $$50$$ $$Hz,$$ represented as a phasor with magnitude $${V_i}$$ and phase angle $$0$$ radian as shown in the figure. The output voltage is represented as a phasor with magnitude $${V_0}$$ and phase angle $$\delta$$ radian. What is the value of the output phase angle $$\delta$$ (in radian) relative to the phase angle of the input voltage?
A
$$0$$
B
$$\pi$$
C
$$\pi /2$$
