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?

• Physics -

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

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

153 kV is the correct answer
