Find electric potential at the center of a Square, if four charges are placed at the corners

Four point charges of 0.02𝝁𝒄, 0.04𝝁𝒄, -0.03𝝁𝒄, and 0.04𝝁𝒄, are placed at the corner A, B, C, and D of a square. Find the potential at the center of the square if each side of the square is 1.5 m apart.

This example number 11.7 from Fsc second year physics book
we have first used Pythagorean theorem to calculate the length of the diagonal and then divided the diagonal by 2 that gives us the value of distance r between the charge Q and center. after that we used the equation of electric potential for net electric potential due to all the four charges. after substituting the values for k Q and r we got the result.

You saved my sanity. Thank you for making this video, I was spinning my wheels for an hour trying to figure out how the math worked for voltage
