(Solved): Two identical magnitude charges with opposite signs are shown in the figure. Determine the value of ...

Two identical magnitude charges with opposite signs are shown in the figure. Determine the value of the electric potential (in \( \mathrm{kV} \) ) at the point \( P \) indicated in the figure. Let \( \mathrm{Q}=62.9 \mathrm{nC}, \mathrm{L}=39.5 \mathrm{~cm} \), and \( \mathrm{D}=13.6 \mathrm{~cm} \). Include negative signs as appropriate for your answer.
