A plastic disk of radius \( R=68.3 \mathrm{~cm} \) is charged on one side with a uniform surface charge density \( 4.75 \mathrm{fC} / \mathrm{m}^{2} \), and then three quadrants of the disk are removed. The remaining quadrant is shown in the figure. With \( V=0 \) at infinity, what is the potential in volts due to the remaining quadrant at point \( P \). which is on the central axis of the original disk at distance \( D=0.473 \mathrm{~cm} \) from the original center?
