Question

A light detector circuit using an ideal photo-diode is shown in the figure. The sensitivity of the photo-diode is $0.5 μ A / μ W$ . With $V_{r} = 6 V$ , the output voltage $V_{0} = - 1.0 V$ for $10 μ W$ of incident light. If $V_{r}$ is changed to $3 V$ , keeping all other parameters the same, the value of $V_{0}$ in volts is
