In the given figure, there are four point charges placed at the vertex of a square of side \( 7 \mathrm{~cm} \). If \( q_{1}=+18 \mu C \), \( q_{2}=-24 \mu \mathrm{C}, q_{3}=+35 \mu \mathrm{C} \) and \( q_{4}=+16 \mu \mathrm{C} \), then find the electric potential at the centre \( \mathrm{O} \) of the square, assume the potential to be zero at infinity.https://bit.ly/YTAI_PWAP https://www.pw.live
