Four equal +6.00-μC point charges are placed at the corners of a square 2.00 m on each side. ( = 1/4π = 8.99 × 109 N · m2/C2)
(a) What is the electric potential (relative to infinity) due to these charges at the center of this square?

    It is four times the potential due to a charge at a single corner.

    Your equation
    1/4¦Ð = 8.99 ¡Á 10^9 N ¡¤ m2/C2
    is obviously incorrect.

    The distance from the center of the square to a corner is R = 1.414 m

    The potential due to a single corner charge is
    kQ/R
    where Q = 6.00*10^-6 C
    k = 8.99 ¡Á 10^9 N¡¤m^2/C^2
